Abstract:
A photonics system includes a transmit photonics module and a receive photonics module. The photonics system also includes a transmit waveguide coupled to the transmit photonics module, a first optical switch integrated with the transmit waveguide, and a diagnostics waveguide optically coupled to the first optical switch. The photonics system further includes a receive waveguide coupled to the receive photonics module and a second optical switch integrated with the receive waveguide and optically coupled to the diagnostics waveguide.
Abstract:
An optical modulator includes an input port, a first waveguide region comprising silicon and optically coupled to the input port, and a waveguide splitter optically coupled to the first waveguide region and having a first output and a second output. The optical modulator also includes a first phase adjustment section optically coupled to the first output and comprising a first III-V diode and a second phase adjustment section optically coupled to the second output and comprising a second III-V diode. The optical modulator further includes a waveguide coupler optically coupled to the first phase adjustment section and the second phase adjustment section, a second waveguide region comprising silicon and optically coupled to the waveguide coupler, and an output port optically coupled to the second waveguide region.
