Abstract
We present a monolithic integrated Raman silicon laser and amplifier based on silicon-on-insulator rib waveguide race-track ring resonator with an integrated p-i-n diode structure. Under reverse biasing, we efficiently reduced the nonlinear loss due to two-photon absorption induced free carrier absorption and achieved continuous-wave net gain and stable, single-mode lasing with output power exceeding 30mW and 10% slope efficiency. The laser emission has high spectral purity with a side mode suppression exceeding 70dB and a laser linewidth of <100 kHz. This ring resonator architecture allows for on-chip integration with other silicon photonics components to provide a highly integrated and scaleable monolithic device. Using the ring resonator architecture, we can build a compact, chip scale Raman amplifier that takes advantage of the resonance effect to increase the effective pump power and reduce the device size. Our simulations suggest that a 3dB net gain can be achieved with 4dB less pump power in a 3cm ring compared to a straight waveguide of the same length.
