US 2003/0072075 A1 · Highly integrated hybrid component for high power optical amplifier application

Abstract

A method and system for providing a highly integrated hybrid component is disclosed. The method and system include providing a triple fiber collimator, a dual isolator/polarization beam deflector and a dual fiber collimator. The triple fiber collimator receives a plurality of pump signals in a first direction and outputs an optical signal in a second direction. The dual isolator/polarization beam deflector is optically coupled to the triple fiber collimator. The dual isolator/polarization beam deflector transmits the pump signals in the first direction, prevents a portion of the pump signals from traveling out of the triple-fiber collimator in the second direction, provides the optical signal in the second direction and prevents a portion of the optical signal from traveling out of the dual fiber collimator in the first direction. The dual fiber collimator receives the optical signal traveling in the second direction and outputs the pump signals traveling in the first direction. Moreover, a partial reflection plate, which reflects a portion of the optical signal to provide a signal tap, may be provided between the dual fiber collimator and the dual isolator/polarization beam deflector.
