Abstract:
A chip for separating light into different wavelengths, comprising:a substrate having first and second edge sections; an input waveguide, on the substrate, having an end for providing light thereto located at the first edge section, the input waveguide extending from the end thereof in a first direction; an optical arrangement which receives the light form the input waveguide and separating the light into a pattern of light of different wavelengths; and a plurality of output waveguides, on the substrate, each receiving light of a respective wavelength from the optical arrangement and transmitting the light, each having an end, from which the light is transmitted, located at the second edge section, and each extending to the end thereof in a second direction which is different from the first direction, wherein the second direction is at an angle of at least 90Â° with respect to the first direction.
