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.

Diagnostic waveguide for optical chip testing

A system and method for backchannel closed loop feedback for channel equalization over Ethernet. Closed loop backchannel feedback for real-time transmitter adaptive equalization is provided for a pair of non-ideal duplex communication channels. The real-time transmitter adaptive equalization enables use of low cost relaxed specification transmitter modules at high data rates.

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.

Hybrid optical modulator

A multi-channel transceiver using a floating frequency grid for multi-channel, optical communication is presented. Transmitter frequencies are permitted to drift, and a receiver is tuned to compensate for drifts in the transmitter frequencies.

Method and system for floating grid transceiver

A transceiver includes an optical waveguide and a first filter optically coupled to the optical waveguide and operable to filter a first optical signal in a first wavelength band propagating downstream. A center wavelength of the first wavelength band is tunable. The transceiver also includes a first receiver optically coupled to the first filter and a second filter optically coupled to the optical waveguide and operable to filter a second optical signal in a second wavelength band propagating downstream. The second wavelength band is different from the first wavelength band. The transceiver further includes a second receiver optically coupled to the second filter to receive the second optical signal and a laser optically coupled to the optical waveguide and operable to output radiation in a third wavelength band propagating upstream. The third wavelength band is different from both the first wavelength band and the second wavelength band.
