Abstract

An optical transmitter including an optical waveguide and N microring resonators (MRRs) coupled to the optical waveguide is provided. In such an optical transmitter each of the N MRRs having a different coupling coefficient determining the amount of coupling to the optical waveguide, wherein N>1. In some embodiments, each of the N MRRs has a different spacing distance from the optical waveguide, wherein the coupling coefficient for each MRR is dependent on the spacing. In some embodiments the optical transmitter further includes an input for receiving N drive signals from a controller, each drive signal shifting the resonant wavelength of the corresponding MRR to control the optical power coupled in the corresponding MRR from the optical waveguide in which an optical signal propagates.
