Abstract
We report on the tunable dual-mode operation of a chirped grating distribut ed-feedback (DFB) laser device with two integrated modulators which act as tuning sections. A transfer-matrix model is used to simulate the amplified spontaneous emission spectrum for a chirped grating DFB laser. Several type s of dual-mode operation are observed for wavelength spacings of 0.5 mm and 1.4 nm corresponding to frequency detunings of 63 GHz and 175 GHz.
