Multi-channel light source and multi-channel optical module using the same

摘要

A multi-channel light source includes a semiconductor optical amplifier for generating light of a wide wavelength band and outputting the generated light through a first end and a second end. The source further includes a Fabry-Perot (FP) resonator for resonating the light inputted from the semiconductor optical amplifier to generate an FP fringe and outputting the FP fringe to the semiconductor optical amplifier. The semiconductor optical amplifier amplifies the FP fringe inputted from the FP resonator and outputs the amplified FP fringe through the first end.
