Sampled-grating DBR laser integrated with SOA and tandem electroabsorption modulator for chirp-control - Electronics Letters
نویسندگان
چکیده
Chirp-controlled optical modulation is demonstrated using a voltage division scheme applied to a long-section phase modulator to compensate for the positive chirp of an electroabsorption modulator arranged in a tandem configuration. Both modulators are integrated with a semiconductor optical amplifier (SOA) and a sampled-grating distributed Bragg reflector (DBR) laser. The effective chirp factor can be controlled from þ1 to 0.86 with less than 2 dB penalty in extinction ratio and insertion loss.
