Title:
METHOD AND APPARATUS FOR SILICON-BASED OPTICALLY-PUMPED AMPLIFICATION USING STIMULATED SCATTERING
Document Type and Number:
WIPO Patent Application WO2004045112
Kind Code:
A3
Abstract:
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.
