Abstract
An optical network unit includes a transmit/receive port and a silicon waveguide optically coupled to the transmit/receive port. The optical network unit also includes a tunable filter coupled to the silicon waveguide and providing a first output for a first frequency band and a second output for a second frequency band. The optical network unit further includes a polarization diverse receiver coupled to the tunable filter and a laser coupled to the tunable filter.

An optical network unit comprising:
- a transmit/receive port;
- a silicon waveguide optically coupled to the transmit/receive port;
- a tunable filter coupled to the silicon waveguide and providing a first output for a first frequency band and a second output for a second frequency band;
- a polarization diverse receiver coupled to the tunable filter;
- and
- a laser coupled to the tunable filter.
An optical network unit comprising:
- a transmit/receive port;
- a silicon waveguide optically coupled to the transmit/receive port;
- a polarization splitter coupled to the silicon waveguide and providing a first output and a second output;
- a first filter coupled to the first output of the polarization splitter, wherein the first filter provides a first output port and a second output port;
- a polarization rotator coupled to the second output of the polarization filter;
- a second filter coupled to the first output port;
- a third filter coupled to the polarization rotator;
- a detector coupled to the second filter and the third filter;
- and
- a laser coupled to the second output port.
A method of operating a transceiver, the method comprising:
- receiving, at a Tx/Rx port, a downstream optical signal comprising data in multiple wavelength bands including an L-band;
- passing the received optical signal through a tunable single channel filter;
- detecting the passed optical signal at a polarization diverse receiver;
- generating an upstream optical signal in the C-band;
- transmitting the upstream optical signal through the tunable single channel filter;
- and
- outputting the upstream optical signal from the Tx/Rx port.
