Abstract
A transceiver is provided for a communication network. The transceiver includes a single laser source configured to output (i) a first optical laser signal at a first wavelength, and (ii) a second optical laser signal at a second wavelength different from the first wavelength. The transceiver further includes a coherent transmitting portion configured to modulate the first optical laser signal for transmission to the communication network, and a coherent receiving portion configured to utilize the second optical laser signal as a local oscillator source.
Claims20
A transceiver for a communication network, comprising:
- a single laser source including a single-wavelength external cavity laser (ECL) integrated with a wavelength-selective optical mode selective mirror (MSM), and configured to output (i) a first optical laser signal at a first wavelength, and (ii) a second optical laser signal at a second wavelength different from the first wavelength;
- a coherent transmitting portion configured to modulate the first optical laser signal for transmission to the communication network;
- and
- a coherent receiving portion configured to utilize the second optical laser signal as a local oscillator (LO) source.
