[0003] A photonic logic gate is a device that uses photons to perform logical operations. In traditional electronic computers, logic gates are constructed from electronic components (such as transistors) to perform logical operations and control data flow. Photonic logic gates, on the other hand, leverage the properties of photons to perform logical operations, offering potential advantages such as high speed and low energy consumption. The implementation of photonic logic gates is typically based on the properties of photons. By manipulating parameters such as photon phase, polarization, and frequency, interactions between photons and information transfer can be achieved, thereby enabling logical operations. The implementation of photonic logic gates is of great significance to fields such as quantum computing, photonic communication, and quantum information processing. However, the development of photonic logic gates faces challenges, such as weak interactions between photons and photon loss. Researchers are continuously exploring new photonic logic gate designs and technical approaches to achieve more efficient and stable photonic logic gates.

[0029] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.
[0030] Example:
[0031] A photon logic gate, which includes a 3D logic NOT gate 01, a 3D logic OR gate 02 and a 3D logic AND gate 03 used in combination, see Figure 8 combination form.
[0032] The specific structures of the 3D logic NOT gate 01, the 3D logic OR gate 02, and the 3D logic AND gate 03 are as follows:
[0033] The structure of the 3D logic NOT gate 01 can be found in Figure 1The 3D logic NOT gate includes a green filter A1.1, a green filter A1.2, a red filter B1.1, a reflector F, a frequency doubling crystal H, and an optical parametric oscillator crystal E. Figure 1 In the X, Y, and Z three-dimensional diagram, the incident light R passes through the green filter A1.1, the reflector F, the frequency doubling crystal H, and the green filter A1.2 in sequence to form the first optical path G1, realizing the red light input to the green light output (see Figure 1 The incident light R passes through the green filter A1.1, the optical parametric oscillator crystal E and the red filter B1.1 in sequence to form a second optical path G2, realizing the green light input to the red light output (see the XY plane in the figure).
[0034] In the 3D logic NOT gate of this embodiment: when green light is input, it passes directly through the green filter and is then converted to red light using OPO technology. A filter is added to remove stray light, and the stray light is reflected out of the logic gate. When red light is input, it passes through the green filter and is reflected upward, continues to reflect and turn, and is then converted to green light using frequency doubling technology. A filter is added to remove stray light, and the stray light is reflected out of the logic gate.
[0035] The structure of the 3D logic OR gate 02 can be found in Figure 2 The 3D logic OR gate includes a green filter A2.1, a green filter A2.2, a filter C, a red filter B2.1, a reflector (not shown), a sum frequency crystal D, and an optical parametric oscillator crystal E; the first incident light passes vertically through the green filter A2.1 to form a third optical path G3, and the second incident light passes vertically through the green filter A2.2 to form a fourth optical path G4. The third optical path and the fourth optical path are arranged in parallel in the same first plane, and the third optical path and the fourth optical path are merged and output through the first output optical path; the first incident light passes through the green filter A2.1 at a 45° angle to form a third optical path G3. Green filter A2.1 directs the light vertically upward to form the fifth optical path G5. The second incident light passes through green filter A2.2 at a 45° angle, directing the light vertically upward to form the sixth optical path G6. The fifth and sixth optical paths are arranged in parallel and perpendicular to the first plane (not shown). The first incident light, after passing through the fifth optical path, merges with the second incident light, after passing through the sixth optical path, and passes through the reflector, sum frequency crystal, filter, optical parametric oscillator crystal, and red filter B2.1 in sequence to form the seventh optical path G7. After passing through the seventh optical path, the light is output through the first output optical path S1.
[0036] In the 3D logic OR gate of this embodiment: when the first incident light and the second incident light are both green, they pass through the green filter and are directly combined to output green light; when one of the first incident light and the second incident light is red and the other is green, the green light passes through the green filter and is directly output green light; the red light is reflected upward, continues to reflect and turn, passes through the sum frequency crystal, and its wavelength becomes longer, and is reflected out of the logic gate by the filter; when the first incident light and the second incident light are both red, the red light is reflected upward by the green filter and turns and passes through the sum frequency crystal to shorten its wavelength. The difference in wavelength between the two beams of light with the same wavelength after passing through the sum frequency crystal is utilized to allow only the light after passing through the sum frequency crystal to pass, and then is restored to red light by the optical parametric oscillator crystal. Finally, a filter is added to remove impurities. If red light is input on both sides, red light is output.
[0037] The structure of the 3D logic AND gate 03 can be found in Figure 3 The 3D logic AND gate includes a red filter B3.1, a red filter B3.2, a filter C, a green filter A3.1, a reflector (not shown), a sum frequency crystal D, and an optical parametric oscillator crystal E; the first incident light passes vertically through the red filter B3.1 to form an eighth optical path G8, and the second incident light passes vertically through the red filter B3.2 to form a ninth optical path G9. The eighth optical path and the ninth optical path are arranged in parallel in the same second plane (not shown), and the eighth optical path and the ninth optical path are merged and output through the second output optical path; the first incident light is at a 45° angle The red filter B3.1 allows the light to pass vertically upward to form the tenth optical path G10. The second incident light passes through the red filter B3.2 at a 45° angle, allowing the light to pass vertically upward to form the eleventh optical path G11. The tenth and eleventh optical paths are parallel and both are arranged perpendicular to the second plane. The first incident light after passing through the tenth optical path merges with the second incident light after passing through the eleventh optical path and passes through the reflector, sum frequency crystal, filter, optical parametric oscillator crystal and green filter A3.1 in sequence to form the twelfth optical path G12. After passing through the twelfth optical path, the light is output through the output optical path S2.
[0038] In the 3D logic AND gate of this embodiment: when the first incident light and the second incident light are both green, they are reflected upward after passing through the red filter, turn and pass through the sum frequency crystal to shorten their wavelength, then pass through the filter again to allow them to pass, and continue to pass through the optical parametric oscillator crystal to be restored to green light. Finally, a filter is added to remove impurities. When green light is input from both sides, green light is output. When one of the first incident light and the second incident light is red and the other is green, the red light passes through the red filter directly and red light is output. The green light is reflected upward, continues to reflect and turn, passes through the sum frequency crystal, and its wavelength is lengthened and reflected out of the logic gate through the filter. When both the first incident light and the second incident light are red, they pass through the red filter directly and red light is output.
[0039] The statistics of red light and green light conversion of 3D logic NOT gate, 3D logic OR gate and 3D logic AND gate are shown in Table 1:
[0040] Table 1 Statistics of red and green light conversion of 3D logic NOT gate, 3D logic OR gate, and 3D logic AND gate
[0041]
[0042] The positional relationship between the sum frequency crystal and the light in this embodiment is detailed in Figure 4 Specifically, the angle between the incident light R and the reflector F is greater than 0° and less than 45°; the angle between the sum frequency crystal D and the incident light R is less than 90° and greater than 0°.
[0043] The positional relationship between the optical parametric oscillator crystal and the incident light in this embodiment is detailed in Figure 5 Specifically, the positional relationship between the optical parametric oscillator crystal E and the incident light R is greater than 0° and less than 180°, the starting point of the reflector F is between the incident light R and the reflected light, and extends in the direction of the reflected light. The reflector is parallel to the optical parametric oscillator crystal E at an angle of 0.11° clockwise.
[0044] Using the solution of this embodiment, the red light wavelength is 650nm and the green light wavelength is 520nm. The details are as follows:
[0045] 3D logic NOT gate: When 650nm red light is injected, the nonlinear effect generates a second harmonic, 520nm green light. Therefore, the nonlinear effect can directly convert 650nm red light into 520nm green light without the need for an external light source. Optical parametric oscillators (OPOs) can be used to convert 520nm green light into red light.
[0046] In a 3D logic OR gate, two 650nm laser beams pass through a sum frequency crystal to generate a 355nm laser beam. This is then filtered by a filter and passed through an optical parametric oscillator crystal to generate a 650nm laser beam, which is then filtered to remove impurities. When a single 650nm laser beam passes through the sum frequency crystal, its wavelength is greater than or equal to the original wavelength and is then intercepted by a filter.
[0047] 3D logic AND gate: When two 520nm laser beams pass through a sum frequency crystal, they generate a 355nm laser beam. This is then filtered by a filter and passed through an optical parametric oscillator crystal to generate a 520nm laser beam. This laser beam is then filtered by a filter. When a single 520nm laser beam passes through the sum frequency crystal, its wavelength is greater than or equal to the original wavelength and is intercepted by a filter.
[0048] In this embodiment, the raw materials, including sum-frequency crystals, optical parametric oscillator crystals, filters, reflectors, and glass, can all be customized online. Glass is used for fixed pipes. A circuit with high and low voltage levels converts red and green laser light into a combined output, which then enters a logic NOT gate. Two circuits with high and low voltage levels convert red and green laser light into a combined output, which then serves as inputs to a logic AND gate and a logic OR gate for testing. Two beams of light from the logic AND and logic OR gates pass through a sum-frequency crystal, filtered with a purple filter, and then passed through a parametric crystal to restore the color. This process can also adjust the material selection based on the angle of the incident light. Finally, a filter splits the output light into two: the green light enters a photosensor circuit without a diode, and the red light enters a photosensor circuit with a diode, connecting the circuits in parallel.
[0049] The schematic diagram of the light-to-electricity process in this embodiment is shown in Figure 6 The incident light passes through the red filter and is divided into two beams. When it is green light, it is incident on the parallel photosensor without germanium diode and outputs a high level. When it is red light, it is incident on the parallel photosensor with germanium diode and outputs a low level.
[0050] See the schematic diagram of the process of electro-conversion of red laser to green laser for details. Figure 7 The power supply is a high- and low-voltage power supply. When current flows from the positive electrode through the transistor, the high voltage passes through, while the low voltage blocks it. When the high voltage is connected in parallel, the green laser and the red laser are connected in parallel. The battery can be reversely charged. When the green laser passes through, the green laser is illuminated. When the red laser passes through, the field-effect transistor is used to disconnect it. When the battery passes through, it charges the battery. When the voltage is low, the battery discharges. There is no circuit between the battery and the negative electrode of the power supply, and no power is supplied. When the green laser passes through, the current is blocked by the transistor. When the current passes through the field-effect transistor, the current passes through, and then the red laser is illuminated. (The battery voltage is lower than the high voltage of the power supply.)

Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations.
