Abstract:
A planar optical waveguide circuit includes an optical modulator, such as that based on a Mach-Zehnder interferometer, that is followed by an in-line optical tap in the form of a 2×2 multi-mode interference coupler that is characterized a reduced tracking error as compared to Y-junction couplers.
