Abstract
An integrated photonic device may include an image detector that comprises an array of pixels. The device may further include an integrated waveguide and a light coupler comprising a light receiving part optically coupled to the integrated waveguide for receiving a light signal. The light coupler may be adapted for coupling a same predetermined spectral band of the light signal to each of a plurality of pixels of the image detector. The light coupler may include a tapered portion, in which the light coupler tapers outward in a direction of propagation, and an end part comprising an elliptically shaped back reflector for reflecting light propagating along the direction of propagation back through the light coupler toward the integrated waveguide.
