H. Okamoto et al., FAST WAVELENGTH SWITCHING FOR 10 GBIT S NRZ SIGNAL WITH A TUNABLE DUPLEX INTEGRATED LIGHT-SOURCE/, Electronics Letters, 31(15), 1995, pp. 1274-1276
Fast wavelength switching with a tunable duplex integrated light sourc
e is reported. The device comprises two distributed Bragg reflector la
sers, two electroabsorption optical switches, a Y-shaped waveguide cou
pler, and an electroabsorption modulator. Using the device, the wavele
ngth of a 10Gbit/s NRZ-modulated optical signal can be switched withou
t bit loss.
