Abstract
In an SOA characteristic evaluation method, the current is supplied to an SOA. An optical output generated by the SOA that have received the current is measured. Transmission light obtained by transmitting the optical output through a wavelength filter and/or a polarizer is measured. The characteristic of the SOA is evaluated on the basis of the measurement result of the optical output and the measurement result of the transmission light without using an optical input to the SOA. An SOA characteristic evaluation apparatus is also disclosed.
