Claim Text:
1. A two-channel silicon photonic transceiver with wavelength control for DEMUX/MUX in DWDM applications, the two-channel silicon photonic transceiver comprising: a transmitter comprising a first optical input port and a second optical input port, a first modulator and a second modulator respectively coupled to the first optical input port and the second optical input port for modulating a first optical signal at a first wavelength and a second optical signal at a second wavelength, and a 2×1 WDM combiner coupled to the first modulator and the second modulator to transmit a first transmission signal combined with the first wavelength and the second wavelength to a first optical output port; a receiver comprising a third optical input port, a second optical output port, a third optical output port, and a two-channel delay-line interferometer coupled between the third optical input port and second and third optical output ports, the third optical input port being configured to receive a second transmission signal combined with the first wavelength and the second wavelength, the second transmission signal being substantially similar to the first transmission signal; wherein the delayed-line interferometer in the receiver is configured to split the second transmission signal to a third optical signal locked at the first wavelength to the second optical output port substantially free of element of the second wavelength and a fourth optical signal locked at the second wavelength to the third optical output port substantially free of element of the first wavelength.
