Photonic circuit with integrated optocoupler

摘要

The invention relates to an integrated photonic device (1) comprising an image detector (2) comprising a pixel array. The apparatus may further comprise an optical coupler 3 including an integrated waveguide 5 and a light receiving section 7 optically coupled with the integrated waveguide 5 to receive an optical signal. The optocoupler 3 can couple the same predetermined spectral band of the optical signal to each of a plurality of pixels of the image detector 2. The optical coupler 3 includes a tapered portion 10 whose optical coupler is tapered outward in the propagation direction and an elliptical rear reflector 10 which reflects the light propagating along the propagation direction through the back surface of the optical coupler toward the integrated waveguide 5 And a distal end 8 including a distal end 13.
