Method and Apparatus For Polarization-Maintaining Fiber Optical Amplification With Orthogonal Polarization Output.
Abstract
A single-polarization fiber optical amplifier and corresponding method is provided capable of amplifying an optical input signal by a fiber optic amplifier constructed of fiber which may be non-polarization-maintaining. The single-polarization fiber optical amplifier provides a direction-selective coupler which receives an optical input at a first port and outputs an optical output at a second port. A fiber optic amplifier is operatively connected to the direction-selective coupler at a bidirectional port for amplifying the optical input. A retro-reflecting orthogonal polarization converter is operatively connected to the fiber optic amplifier, reflecting the amplified optical input from the fiber optic amplifier in a return direction through the fiber optic amplifier and in an orthogonal polarization to the amplified optical input. The direction-selective coupler outputs the reflected amplified orthogonal optical input at the second port as the optical output of the direction-selective coupler
