Abstract: An optical coupling adaptor couples an optical fiber to a photonic integrated circuit (PIC) chip. The adaptor once connected to the PIC chip forms a chip-adaptor assembly. The photonic integrated circuit (PIC) chip has a plurality of inverted taper waveguides having an enlarged optical mode. The optical coupling adaptor has a first section having a plurality of ridge waveguides between layers of cladding and also separated laterally by cladding and a second section abutting the first section, the second section having a plurality of trenches each filled with an optical polymer that Once cured has a refractive index that matches that of the ridge waveguides. The optical coupling adaptor is adhered to the PIC chip using the optical polymer as an adhesive such that the optical polymer in the trenches once cured form polymer waveguides that confine the enlarged mode of the inverted taper waveguides.

Abstract: A photonic platform based polarization controller providing a fixed target polarization is disclosed. The polarization controller has a polarization rotator splitter splitting the beam into first and second feeds corresponding to first and second orthogonal polarization components. A first Mach-Zehnder interferometer (MZI) stage provides a first phase delay between the first and second feeds based on a first control signal, and a first mixer mixes the first and second feeds to provide third and fourth feeds. A second MZI stage provides a second phase delay between the third and fourth feeds based on a second control signal, and a second mixer mixes the third and fourth feeds to provide fifth and sixth feeds. A third MZI stage provides a third phase delay between the fifth and sixth feeds based on a third control signal, and a third mixer mixes the fifth and sixth feeds to provide the fixed target polarization. An optical tap splits a portion of the beam.

Abstract: A tunable optical directional coupler includes a first waveguide and a second waveguide proximal to the first waveguide, the first and second waveguides defining a light-coupling coefficient. The tunable optical directional coupler also includes a doped junction having a refractive index that is responsive to an applied bias voltage wherein the refractive index is changeable to enable tuning of the light-coupling coefficient. The tunable optical directional coupler may be used to split power, tune the phase, split polarizations or to tune a ratio of a tap-monitor.

Abstract: A bidirectional optical tap-monitor is described for detecting an optical signal power carried by a through waveguide. The tap-monitor comprises a tap waveguide placed near the through waveguide, and a single waveguide-type photodetector for detecting a fraction of the optical signal power coupled from the tap waveguide. The tap waveguide includes two ports at opposite ends of the tap waveguide and the waveguide-type photodetector includes two ports that are connected respectively to the two ports of the tap waveguide. When light travels through the through waveguide in one direction, the coupled fraction of the optical signal power is fed to the photodetector via one of the two ports of the tap waveguide, and when light travels through the through waveguide in the opposite direction, the coupled fraction of the optical signal power is fed to the photodetector via the other one of the two ports of the tap waveguide. The bidirectional optical tap-monitor is operable in either a forward-propagating or a backward-propagating direction.
