Abstract:
An optical device, comprising a chirped waveguide grating router, wherein the chirped router comprises:(a) an input port configured to receive an incoming optical signal;(b) a set of grating arms configured such that the incoming optical signal is propagated through the set of grating arms; and(c) a plurality of output ports configured to transmit one or more outgoing optical signals resulting from propagation of the incoming optical signal through the set of grating arms, wherein:when the incoming optical signal received at the input port of the chirped router corresponds to a first wavelength band, propagation of the incoming optical signal through the set of grating arms causes the chirped router to function as an optical splitter; andwhen the incoming optical signal received at the input port of the chirped router corresponds to a second wavelength band, propagation of the incoming optical signal through the set of grating arms causes the chirped router to function as an optical router.
