摘要： A semiconductor-based Raman ring amplifier is disclosed. A method according to aspects of the present invention includes directing a pump optical beam having a pump wavelength and an input pump power level from an optical waveguide into a ring resonator. The optical waveguide and ring resonator are comprised in semiconductor material. A signal optical beam having a signal encoded thereon at a signal wavelength is directed from the optical waveguide into the ring resonator. The pump optical beam is resonated within the ring resonator to increase a power level of the pump optical beam to a power level sufficient to amplify the signal optical beam via stimulated Raman scattering (SRS) within the ring resonator. A free carrier concentration in the optical waveguide and the ring resonator is reduced to reduce attenuation of the pump optical beam and the signal beam.

摘要： Instead of monitoring the optical power coming out of a waveguide, a direct method of monitoring the optical power inside the waveguide without affecting device or system performance is provided. A waveguide comprises a p-i-n structure which induces a TPA-generated current and may be enhanced with reverse biasing the diode. The TPA current may be measured directly by probing metal contacts provided on the top surface of the waveguide, and may enable wafer-level testing. The p-i-n structures may be implemented at desired points throughout an integrated network, and thus allows probing of different devices for in-situ power monitor and failure analysis.
