Finely tunable 10-Gb/s signal wavelength conversion from 1530 to 1560-nm region using a super structure grating distributed Bragg reflector laser

Finely tunable wavelength conversion of a 10-Gb/s signal is demonstrated to wavelengths ranged from 1530 to 1560 nm with spacings of 0.5 nm and accuracy of /spl plusmn/0.05 nm, where the Er/sup 3+/ doped optical fiber amplifier has optical gain, by using a super structure grating distributed Bragg reflector laser. Transmission of a wavelength-converted 10-Gb/s signal within the entire target wavelength range over a 100-km optical fiber is also demonstrated using a dispersion-shifted optical fiber.
