Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0029] As shown in the above structure, the function of this structure is to output the wave of any polarization state input from the left input port from the upper port and the right port in the form of integer ratio power. figure 1 Figure 4 in Figure 4 shows the corner of the waveguide after deleting a dielectric column. The purpose of deletion is to allow more energy to be introduced into the upper port, while reducing the figure 1 The echo reflection of the dielectric column shown in Figure 5 in Figure 5 greatly reduces the regular reflection part of the light energy. As an example, figure 1 The waveguide defect dielectric column 5 shown in Figure 5 is taken as a negative uniaxial crystal, and the background dielectric column 6 is taken as a positive uniaxial crystal. constant to control the power distribution of the light waves of each polarization sta...

Abstract

The invention discloses a full-polarization-state integer ratio power distributor with a photonic crystal waveguide. The full-polarization-state integer ratio power distributor comprises the photonic crystal waveguide formed in a photonic crystal with a complete band-gap; the photonic crystal consists of a background dielectric cylinder array; the photonic crystal waveguide consists of a transverse waveguide and a perpendicular waveguide perpendicularly connected with the transverse waveguide; one end of the transverse waveguide is an input end, and the other end of the transverse waveguide is an output end; the perpendicular waveguide is another output end; and waveguide flaw dielectric cylinders are arranged in the middle of the transverse waveguide. The full-polarization-state integer ratio power distributor is small in structural size and high in light transmission efficiency, can be integrated conveniently and efficiently, is suitable for large-scale light path integration, and can realize a full-polarization-state integer ratio power distribution function.

Description

technical field [0001] The invention relates to the field of tiny optical power distribution, in particular to a tiny optical full polarization state integer ratio power divider based on photonic crystal technology. Background technique [0002] The photonic crystal waveguide integer ratio power divider is an indispensable optical passive device in the photonic crystal integrated optical circuit, and is an indispensable part of various optoelectronic integrated components. The photonic crystal waveguide integer-ratio power divider can ideally distribute the light energy at the output end in an integer ratio without obvious reflection and scattering losses. Although a large number of optical path structures have tried to solve the loss of optical energy caused by the intrinsic refractive index and waveguide characteristics, few of them have achieved the desired effect. [0003] At present, most photonic crystal integer ratio power dividers are designed on the basis of one po...
