Abstract
Disclosed herein is an optical filter configured for wavelength division and multiplexing capable of transmitting and receiving signals. The optical filter includes an optical waveguide configured to receive at an input multiple signals with different wavelengths. The optical filter includes a plurality of channels coupled at different locations along a length of the optical waveguide. Each of the plurality of channels is configured to transmit a respective one of the multiple signals. A number of ring filter stages in a first channel of the plurality of channels that is closer to the input of the optical waveguide is greater than a second channel in the plurality of channels further away from the input of the optical waveguide.
