G. Alibert et al., SUBNANOSECOND TUNABLE LASER USING SINGLE ELECTROABSORPTION TUNING SUPER STRUCTURE GRATING, IEEE photonics technology letters, 9(7), 1997, pp. 895-897
A new tunable laser structure using a single electroabsorption (EA) tu
ning super structure grating section for fast wavelength switching ope
ration, has been realized. The tuning mechanism of this absorption cha
nge distributed Bragg reflector (DBR) laser is based on a localized ab
sorption variation induced in a multielectrode EA-SSG section. These d
evices exhibit a 2.5-nm tuning range with three modes and a switching
time, between two successive wavelength channels, shorter than 250 ps.
The output power variation under tuning is lower than 1.2 dB.
