Fully Integrated, Multiport, Planar-Waveguide, Spectral Comparators and Multiplexers Based on Lithographic Holography
Abstract
Several multiplexer layouts based on holographic Brag reflectors were designed and fabricated in a preliminary device water Fabrication results constitute. for the first time the successful application of HBRs to wavelength division multiplexing. Measured device performance indicates that the photolithographic fabrication process has reduced multiplexer designs to practice essentially perfectly. Device apodization and engineering of multiplexer spectral transfer functions based on partial writing and offsetting of diffractive contours is shown to function with high fidelity. A compact-footprint multiplexer based on overlay of several HBRs on the same area was demonstrated. A novel approach to the control and mitigation of waveguide birefringence has been devised successfully.
