摘要： An optical polarization modulator (OPM) for use in an optical communication system includes two polarizing beam splitters (PBSs) and an adjusting stage coupled between the PBSs. One PBS receives an input optical signal with an arbitrary state of polarization (SOP) and splits it into its TE and TM components. The adjusting stage can change the amplitude and/or relative phase between the TE and TM components to help achieve a desired state of polarization (SOP). The ACS and PCS may include MZIs to both adjust the amplitude and the relative phase difference between the TE and TM components. Alternatively, the OPM may include an amplifier and a phase shifter for each component. The second PBS combines the adjusted components to form the output signal with a desired SOP. Another embodiment of the OPM includes an Y-junction coupler, two plasma optical-effect silicon phase shifter stages, a 2×2 3-dB coupler and a PBS. The Y-junction coupler splits the incoming optical signal into two equal portions (containing TM and TE components). The first stage adjusts the relative phase between the portions. The 2×2 3-dB coupler allows the phase adjusted portions to interact to adjust the amplitude. The second stage adjusts the phase difference between the two portions for TE and TM components and outputs the adjusted portions to the PBS via polarization maintaining fibers. The PBS then combines the TE component of one portion with the TM component of the other portion to form an output signal with the desired SOP.

摘要： A Raman ring resonator based laser and wavelength converter method and apparatus. In one aspect of the present invention, the disclosed method includes directing a first optical beam of a first wavelength and a first power level into a first ring resonator defined in a semiconductor material. Emission of a second optical beam of a second wavelength is caused in the first ring resonator by propagating the first optical beam around the first ring resonator. The first power level is sufficient to cause the emission of the second optical beam. The first optical beam is directed out of the first ring resonator after a round trip of the first optical beam around the first ring resonator. The second optical beam is recirculated around the first ring resonator to further stimulate the emission of the second optical beam in the first ring resonator.

摘要： A semiconductor-based optical amplifier using optically-pumped stimulated scattering includes an optical signal source (pump) and a wavelength selective coupler. The coupler is connected to receive an input optical signal and the pump signal and output the combined signals in a waveguide having a semiconductor core. The intensity of the pump signal is selected so that stimulated scattering occurs when the pump signal is propagated in the semiconductor core. Further, the wavelength of the pump signal is selected so that the stimulated scattering causes emission of a signal shifted in wavelength to be substantially equal to the wavelength of the optical input signal. Consequently, the input signal is amplified as it propagates with the pump signal. The amplifier can be disposed between reflectors to form a laser.
