Abstract:
An optical device comprising a 1x2 optical coupler on a planar substrate and a waveguide structure on the planar substrate, the waveguide structure having a first waveguide arm and a second waveguide arm coupled to the 1x2 optical coupler. The device also comprises an optical resonator on the planar substrate, wherein the optical resonator is optically coupled to the first waveguide arm and the optical resonator is substantially athermalized.
Abstract:
An apparatus includes an AWG demultiplexer having first and second adjacent input ports. The first input port is configured to receive a first WDM data-bearing signal, the second input port is configured to receive a first WDM LO signal.. The first and second input ports are located such that individual channels of said WDM data-bearing signal route to a first set of output ports, and individual channels of said WDM LO signal route to a second set of output ports interleaved with the first set.
Abstract:
An apparatus includes an optical splitter, an optical intensity combiner, first and second Mach-Zehnder interferometers, and first and second drive electrodes. The first Mach-Zehnder interferometer connects a first optical output of the optical intensity splitter to a first optical input of the optical intensity combiner. The second Mach- Zehnder interferometer connects a second optical output of the optical intensity splitter to a second optical input of the optical intensity combiner. The first drive electrode is located between and connected to a pair of semiconductor junctions along first internal optical arms of the Mach-Zehnder interferometers. The second drive electrode is located between and connected to a pair of semiconductor junctions along second internal optical arms of the Mach-Zehnder interferometers.
