We have developed spectral separation devices for processing femtosecond pulses. These devices are based on an optical coupler structure with fiber gratings. In a computer simulation, we confirmed that these devices could extract<1nm bandwidth light with 80% efficiency. We fabricated the spectral separation devices using single mode fibers and highly Ge-doped fibers. These devices successfully extracted narrow spectral light of 0.3nm bandwidth with 37% efficiency from femtosecond pulses of 40nm bandwidth. We also fabricated 2-channel spectral separation devices, which could extract the light from each grating channel.
