A. Ramdane et al., Tunable distributed Bragg reflector laser-electroabsorption modulator based on identical active layer monolithic integration approach, ELECTR LETT, 35(19), 1999, pp. 1637-1639
The monolithic integration of a tunable DBR laser and electroabsorption mod
ulator is reported. A common strained multiquantum well active layer is use
d for the three optical functions of this device. A tuning range of 7.4nm a
nd an extinction ratio higher than 12dB for all the eight accessible channe
ls are reported at 1.55 mu m.
