Silicon-Photonics Multi-Wavelength Common-Gain Tunable Laser Providing Both Source And Pump For An Amplified Transceiver

We propose and demonstrate a silicon-photonics-based laser that outputs multiple independently tunable wavelengths using a single It& gain element. We use it to generate a C-band tunable source for a coherent transceiver and simultaneously a 1480-nm source to pump an Er-doped fiber amplifier on the transmitter output.
