Optical coupling losses from a semiconductor optical amplifier (SOA) to a single-mode fiber are analyzed using laser coupled-mode theory. Two wedged-cylindrical fiber lenses are fabricated to reduce the optical losses due to their well-matched mode sizes. A semiconductor optical amplifier (SOA) module and its fabrication are introduced. The maximum gain of the SOA module is more than 14 dB with a polarization sensitivity less than 1dB, and its gain fluctuation is no more than 0.5 dB.
