英文摘要	A fiber input/output type semiconductor optical amplifier module is disclosed. A semiconductor laser amplifier chip (110) is provided for direct amplification of signal light beam. An optical coupling between the semiconductor laser chip (110) and input/output fibers (101, 102) is taken with a remote coupling using a parallel light beam. Collimator lenses (111, 112, 113, 114, 115) are provided for converting the lightwave signal into parallel light beam. Two optical isolators (121, 122) are provided for preventing self-lasing of the semiconductor laser chip (110). One of the isolators (121, 122) is inserted in an input side of the semiconductor laser chip (110), and the other is in an output side of the chip. An interference filter (131) and a beam splitter (141) are disposed in the output side of the semiconductor laser chip (110). The beam splitter (141) splits the output signal of the semiconductor laser chip (110) for monitoring an output power of the chip.
