PROBLEM TO BE SOLVED: To provide a multi-channel optical transmission light source which compensates for an optical output, and is compact and fast at low power consumption and low cost. SOLUTION: The multi-channel optical transmission light source has a VCSEL array 12 in which surface emitting lasers are integrated by four channels, and a multiplexer integration SOA array 14 obtained by integrating mirrors 15 by four channels, SOAs 13 by four channels for amplifying each light led from each of the mirrors 15, and a multiplexer 16 for multiplexing the light output from each of the SOAs 13. High frequency wirings 17 to the VCSEL array 12 are provided by four channels on a surface of the multiplexer integration SOA array 14 around the mirrors 15, and the VCSEL array 12 is mounted on the high frequency wirings 17 as a flip chip so that each light from each of the surface emitting lasers of the VCSEL array 12 is incident on the mirrors 15.
