Wavelength converter apparatus for ultra-high speed optical signal process

摘要

The present invention relates to a wavelength converter apparatus for ultra-high speed optical signal process. So, the present invention (a)embodies a wavelength converter which does not need an outer pump light by composing a semiconductor optical amplifier-ring type laser and (b)provides a wavelength converter apparatus for ultra-high speed optical signal process which embodies to be always operated wavelength conversion to be always possible within the amplifying bandwidth(about 40 mm) of SOA by a wavelength-tunable optical band pass filter deposited in a laser resonator. Therefore, the present invention (a)does not need the external pump light because converted wavelength is tuned within the amplifying bandwidth of SOA, and the own laser oscillation wavelength is used as a pump light, (b)can be used as an original WDM optical wavelength converter because the present invention can be used in the range 1.55 um, and (c) can be used not only as an ultra-high speed optical communication element of next generation(such as ultra-high speed all-optical wavelength converter over 10 Gbps) but also as an optical switch element (such as an optical signal connector) because the reaction speed of SOA which is used as a wavelength converter is up to sub-pico second and the wavelength conversion is possible up to the speed terra bit per a second.
