Description

Technical Field

[0001] The present application relates to the technical field of superlens, and in particular, to a system for modulating double-peak Gaussian light and a system for outputting single-peak Gaussian light. Background Art

[0002] With the rapid development of science and technology, optical technology plays an increasingly important role in various fields. Among many optical phenomena, Gaussian light, as a beam with unique properties, has received widespread attention and application. In recent years, double-peak Gaussian light sources have gradually become popular in the field of optics due to their unique physical properties and wide potential applications. Double-peak Gaussian light is a special beam distribution, and its light intensity distribution curve shows two obvious peaks. The popularity of this light source is mainly due to its unique physical properties and simplified preparation methods. Through precise laser control and beam shaping technology, double-peak Gaussian light can be stably generated and widely used in laboratories and industrial production.

[0003] Although double-peak Gaussian light has unique advantages in certain applications, due to the uneven intensity distribution of double-peak Gaussian light, the light intensity between the two peaks is low, which may lead to reduced energy utilization efficiency in applications. In addition, the stability of double-peak Gaussian light is relatively poor and is easily affected by environmental factors such as temperature, humidity, and vibration, which limits its application in high-precision optical systems. In contrast, single-peak Gaussian light has many advantages. First, the light intensity distribution of single-peak Gaussian light is uniform, and the energy is concentrated in the center of the light beam, which is conducive to improving energy utilization efficiency. Secondly, single-peak Gaussian light has good stability and directionality, can maintain the shape and intensity of the light beam during long-distance transmission, and has good applications in many fields.

[0004] Therefore, the technical problem of how to modulate double-peak Gaussian light into single-peak Gaussian light has become an issue that people urgently need to solve. Utility Model Content

[0044] Double-peak Gaussian light is emitted by a specific light source, such as VCSEL (Vertical Cavity Surface Emitting Laser); double-peak Gaussian light has a double peak property. Bimodality refers to two obvious peaks in the light intensity distribution, which may be symmetrical about the central axis or may not be on the same straight line. Compared with single-peak Gaussian light, the light intensity distribution of double-peak Gaussian light is more complex. Since VCSEL emits a high-power optical laser beam vertically from the top surface, this characteristic makes the beam easy to control and integrate, and VCSEL has a high-efficiency photoelectric conversion capability, can provide stable and high-quality laser output, and VCSEL has a long service life and high reliability, suitable for various complex environments, and VCSEL is small in size and easy to integrate into various optical systems, including superlens systems, so using VCSEL as a light source is a preferred solution for this application.

[0045] VCSELs usually emit double-peak Gaussian light. However, subsequent application scenarios may require the light source to have some characteristics of single-peak Gaussian light, so there is a practical need to modulate double-peak Gaussian light into single-peak Gaussian light.

[0046] Single-peak Gaussian light is a special light beam whose light intensity distribution is Gaussian, that is, the maximum light intensity is at the center and gradually decreases as the distance from the center increases. In three-dimensional space, the light field amplitude of this beam is Gaussian, and it propagates divergently in the propagation direction. Single-peak Gaussian light has the same brightness distribution in the vertical and horizontal directions, showing excellent symmetry.

[0047] Based on this, the present application provides a system for modulating double-peak Gaussian light. In the following, an exemplary embodiment according to the present application will be described with reference to the accompanying drawings. The system for modulating double-peak Gaussian light includes: a superlens array, the superlens array includes a plurality of sub-superlenses, and the arrangement of the superlens array is consistent with the arrangement of the light source array; the plurality of sub-superlenses all have a collimated phase to collimate the double-peak Gaussian light emitted by the corresponding sub-light sources in the light source array; and, if the phase distribution centers of the plurality of sub-superlenses are rotated around the projection position of the center of the light source array on the superlens array to a matching reference angle, the phase distribution centers of the plurality of sub-superlenses after rotation overlap with the geometric center of the corresponding sub-superlens, and the reference angle is less than 360 degrees, so that the light beam modulated by the superlens array is a single-peak Gaussian light.

[0048] like Figure 1 As shown in the figure, the intensity distribution of the double-peak Gaussian light is annular, with the horizontal direction being the X direction and the vertical direction being the Y direction. The light intensity will show two peaks in the X or Y direction. Figure 2 As shown, the intensity distribution of single-peak Gaussian light is circular, and the closer to the center of the circle, the stronger the light intensity.

[0049] The inventors of the present application unexpectedly discovered that, under the premise that the phase distribution centers of multiple sub-superlenses coincide with their geometric centers, if the phase distribution centers of the multiple sub-superlenses are rotated by a matching reference angle around the projection position of the center of the light source array on the superlens array, the double-peak Gaussian light emitted by the light source array will be modulated by the superlens array into a single-peak Gaussian light.

[0050] In some embodiments, the reference angle is optionally in the range of 0.3 to 1.5 degrees. Without wishing to be bound by any theory, if the reference angle is less than 0.3 degrees, the modulated light beam is still a double-peaked Gaussian light; if the reference angle is between 0.3 and 1.5 degrees, the modulated light beam is a single-peaked Gaussian light; if the reference angle is greater than 1.5 degrees, the light intensity of the modulated light source will be unstable and jitter in multiple places.

[0051] In some embodiments, optionally, the reference angles of the sub-metalenses are the same. Figure 3As shown, the sub-superlens is hexagonal in shape, and its geometric center 301 is located at the geometric center of the hexagonal lattice. After the sub-superlens is rotated and offset, the phase distribution center 302 of the sub-superlens will overlap with the geometric center 301 of the sub-superlens. It should be noted that for each sub-superlens on the superlens array, the corresponding phase distribution center can be rotated and offset around the projection position of the center of the light source array on the superlens array at the same reference angle, so that the phase distribution center can overlap with its geometric center. In other words, the reference angle of rotation of each sub-superlens in the superlens array is the same.

[0052] In some embodiments, optionally, the number of sub-super lenses in the super lens array is greater than or equal to the number of sub-light sources in the light source array. When the number of sub-super lenses in the super lens array is equal to the number of sub-light sources in the light source array, all sub-super lenses and sub-light sources present a one-to-one correspondence. Optionally, the setting of sub-super lenses can be increased on the periphery of the super lens. Due to the influence of the assembly process of the light source array and the super lens array or other reasons, preparation errors are inevitable, and when the errors are large, some edge sub-light sources will not have corresponding sub-super lenses. Therefore, by adding the configuration of sub-super lenses at the edge of the super lens array, the fault tolerance of the super lens array installation can be improved. Specifically, one or two circles of super lenses are set on the periphery of the super lens array.

[0053] Preferably, the superlens array and the light source array have the same arrangement, that is, the sub-superlenses and sub-light sources are arranged in a one-to-one correspondence. It should be understood that the present application does not limit the arrangement of the superlens array or the light source array. No matter which arrangement is adopted, as long as the light source array can emit double-peak Gaussian light, it is within the protection scope of the present application; the arrangement of the light source array can be a tetragonal lattice arrangement, then the arrangement of the superlens array should also be a tetragonal lattice arrangement, and the sub-superlenses in the superlens array and the sub-light sources in the light source array are arranged in a one-to-one correspondence. The arrangement of the light source array also includes other methods, such as Figure 4 As shown, the light source array is arranged in a hexagonal lattice arrangement.

[0054] The shape of the sub-superlens can be set to different shapes under the premise that the arrangement of the superlens array remains unchanged. Optionally, its shape is circular, square, hexagonal or other regular polygons. Figure 5 As shown, the sub-super lenses are circular in shape and arranged in a hexagonal lattice array. Figure 6 As shown, the sub-super lenses are hexagonal in shape and arranged in a hexagonal lattice array.

[0055] Preferably, the sub-light sources are arranged on the front focal plane of the sub-super-lens. Since the sub-light sources are arranged one-to-one with the sub-super-lenses, the intervals between the sub-light sources are equal to the intervals between the corresponding sub-super-lenses.

[0056] In some embodiments, preferably, the modulation phase of the sub-metalens is a hyperbolic phase. The hyperbolic phase is used to collimate the light beam emitted by the sub-light source. The phase distribution expression of the hyperbolic phase is:

[0057]

[0058] In formula (1), represents the phase distribution of the sub-superlens, f is the focal length of the sub-superlens, k is the wave number, x is the coordinate of the corresponding position on the sub-superlens relative to the center of the phase distribution in the X-axis direction, and y is the coordinate of the corresponding position on the sub-superlens relative to the center of the phase distribution in the Y-axis direction.

[0059] In a second aspect, the present application further provides a system for outputting single-peak Gaussian light, comprising: a light source array, wherein the light beam emitted by each sub-light source in the light source array is double-peak Gaussian light; a system for modulating double-peak Gaussian light as described in the technical solution of the first aspect and any optional solution thereof;

[0060] The light source array and the super lens array are arranged on the same optical axis, and the light source array is arranged on the front focal plane of the super lens array.

[0061] The size of the sub-superlens is related to the total divergence angle of the sub-light source and the focal length of the sub-superlens. The size of the sub-superlens satisfies:

[0062] D 2 ≥D 1 +f*2*tan(θ 1 ); (2)

[0063] In formula (2), D 2 is the diameter of the sub-superlens, D 1 is the diameter of the sub-light source, θ 1 is the half-angle divergence angle of the sub-light source, and f is the focal length of the sub-superlens. It can be concluded from Formula 2 that the diameter of the sub-superlens is positively correlated with the diameter of the sub-light source and is positively correlated with the half-angle divergence angle of the sub-light source.

[0064] The focal length of the sub-superlens satisfies:

[0065]

[0066] Among them, θ 2 is the half-angle divergence of the light beam collimated by the electron super-lens.

[0067] In some embodiments, optionally, the full-angle divergence angle of the light beam obtained after collimation by the sub-superlens is less than or equal to 6 degrees.

[0068] In some embodiments, optionally, each sub-light source in the light source array is a vertical cavity surface laser emitter (VCSEL).

[0069] It should be understood that the light emitted by the light source array is a double-peak Gaussian light, that is, after all the light beams emitted by all the sub-light sources constituted by it are aggregated, a double-peak Gaussian distribution is formed on the target plane. The above-mentioned target plane is set perpendicular to the optical axis of the system. The sub-super lens in the super lens array collimates the light beam emitted by the corresponding sub-light source, and on the premise that the phase distribution center of the sub-super lens coincides with its geometric center, the reference angle is rotated according to the projection position of the center of the light source array on the super lens array, and finally the double-peak Gaussian light emitted by the light source array is modulated into a single-peak Gaussian light. Therefore, the implementation scheme of the present application is collimation plus rotational offset, both of which are indispensable. In addition, rotational offset cannot be understood as translation. If the phase distribution center of the sub-super lens is translated only in the X-axis and Y-axis directions, the overall light will change from overall vertical emission to overall deflection emission, and its light intensity distribution remains unchanged, and it is still a double-peak Gaussian light.

[0070] Example 1

[0071] The sub-light sources in the light source array are VCSELs, and the total divergence angle of each sub-light source is 25 degrees. The sub-light sources are arranged in a hexagonal lattice array, and the light-emitting area of ​​the entire light source array is 1.2mm*1mm. The superlens array contains the same number of sub-superlenses as the sub-light sources, and the geometric positions of the sub-superlenses correspond one-to-one to the sub-light sources. The superlens array is set to cover the light-emitting surface of the light source array. The light source array is fixedly connected to the superlens array through a support frame, the light source array is coaxially arranged with the superlens array, and the light source array is arranged on the front focal plane of the superlens array. Since the thickness of the superlens is less than 1mm, the thickness of the entire collimation device is less than 1.5mm.

[0072] like Figure 7 As shown, it is a top view of the light source array and the superlens array. In this embodiment, the phase distribution center of the sub-superlens is rotated and offset by rotating the sub-superlens and the light source center. The vertical "cross" in the figure represents the geometric center of each sub-superlens, and the "M" in the figure represents the position of the phase distribution center of the sub-superlens after rotation and offset. The geometric center of the superlens array coincides with the light source array. The phase distribution center of all sub-superlenses is rotated 1 degree clockwise with the projection position of the light source array center on the superlens array as the center. It can be seen from the figure that the degree of rotational offset of the sub-superlens is positively correlated with the distance from the projection position. After the sub-light sources at different positions are collimated by the sub-superlens, all collimated light beams with different light intensity distributions will form a light spot with a single-peak Gaussian light intensity distribution in the far field. As shown Figure 8 As shown in the figure, the light spot measured within 5m after the light source array is modulated by the super lens array. It can be seen from the figure that the light spot is distributed in a circular shape, the light intensity is high in the middle, and the light intensity gradually decreases from the center to the edge, which conforms to the light intensity distribution law of single-peak Gaussian light. Fig. 9 As shown, Fig. 9is the light intensity distribution diagram of the X-axis section of the light source. It can be seen from the figure that the light intensity distribution is high in the middle and low on both sides, which conforms to the light intensity distribution law of single-peak Gaussian light; Fig.10 As shown, Fig.10 is the light intensity distribution diagram of the Y-axis section of the light source. It can be seen from the figure that the light intensity distribution is high in the middle and low on both sides, which conforms to the light intensity distribution law of single-peak Gaussian light. Fig.11 As shown in the figure, it is the light spot distribution diagram measured by the light source 5m away. It can be seen from the figure that the light intensity distribution law of single-peak Gaussian light is still presented, which is high in the middle and low around.

[0073] Cancel the rotation angle and perform data analysis on the light modulated by the superlens array again. Fig.12 As shown in the figure, the phase distribution center of the sub-superlens is not deviated, and the light is modulated by it to form a two-dimensional light spot on the target plane. It can be seen in the figure that the light spot is ring-shaped, with low light intensity in the middle. From the center to the edge, the light intensity increases first and then decreases, which is consistent with the distribution characteristics of double-peak Gaussian light. Fig.13 As shown, Fig.13 This is the intensity distribution diagram of the X-axis section of the collimated light spot. It can be seen from the figure that the intensity trend is from the lowest value to the peak value, then drops a certain amplitude, then rises to the peak value, and then drops to the lowest value. The distribution of light intensity in the figure clearly shows two peaks, which is consistent with the intensity distribution of double-peak Gaussian light; Fig.14 As shown, Fig.14 This is the intensity distribution diagram of the Y-axis section of the collimated light spot. It can be seen from the figure that the intensity trend is from the lowest value to the peak value, then drops a certain amplitude, then rises to the peak value, and then drops to the lowest value. The distribution of light intensity in the figure clearly shows two peaks, which is consistent with the intensity distribution of double-peak Gaussian light; Fig.15 As shown in the figure, it is the distribution diagram of the light spot measured at a distance of 15m. It can be seen from the figure that the light spot is obviously ring-shaped, with low brightness in the middle and a light intensity distribution pattern of high first and low later from the center to the surroundings. After testing, it was found that the superlens array without rotational offset cannot modulate the double-peak Gaussian light emitted by the light source array into a single-peak Gaussian light.

[0074] The above is only a specific implementation of the embodiment of the present application, but the protection scope of the embodiment of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or replacements within the technical scope disclosed in the embodiment of the present application, which should be included in the protection scope of the embodiment of the present application. Therefore, the protection scope of the embodiment of the present application shall be based on the protection scope of the claims.
