INTEGRATED DOUBLE-FREQUENCY OPTICAL RADIATION SPLITTER Russian patent published in 2025 - IPC G02B6/122 

FIELD: optics.

SUBSTANCE: invention relates to integrated optics and specifically to optical radiation splitters. Integral double-frequency optical radiation divider contains four Y-shaped dividers, two directional couplers and two modified dividers, which are combined Y-shaped dividers, where the first input of the integrated double-frequency optical radiation divider is connected to the first input of the first Y-shaped divider, second input of first Y-shaped divider is connected to first inputs of fourth directional coupler, third input of first Y-shaped divider is connected to second inputs of fifth directional coupler, third input of fourth directional coupler is connected to first input of eighth Y-shaped divider, third input of the eighth Y-shaped divider is connected to the fourth input of the integral double-frequency optical radiation divider, second input of the eighth Y-shaped divider is connected to the fourth input of the fifth directional coupler, first input of fifth directional coupler is connected to fourth input of second modified divider, third input of fifth directional coupler is connected to second input of seventh modified divider, first input of seventh modified divider is connected to fourth input of fourth directional coupler, second input of fourth directional coupler is connected to third input of second modified divider, first input of second modified divider is connected to second input of third Y-shaped divider, first input of third Y-shaped divider is connected to second input of integral double-frequency optical radiation divider, third input of third Y-shaped divider is connected to third input of seventh modified divider, fourth input of seventh modified divider is connected to third input of sixth Y-shaped divider, first input of sixth Y-shaped divider is connected to second input of second modified divider, second input of the sixth Y-shaped divider is connected to the third input of the integral double-frequency optical radiation divider.

EFFECT: wider range of optical radiation dividers, as well as broader functional capabilities of integral dividers, which consists in the possibility of operating simultaneously with two optical radiation sources.
