Title: Chirped-grating tunable DFB laser: novel laser diode with broader continuous tuning range
Abstract: A novel wavelength-tunable semiconductor laser is proposed, where use is made of a chirped grating. Threshold conditions of this chirped grating tunable (CGT) distributed feedback (DFB) laser with three electrodes have been numerically studied on the basis of coupled-mode equations with transfer-matrix forms. It has been found that the DFB lasers with gratings properly chirped may have enhanced single-mode continuous tunability. A preliminary experimental result has shown a 7.3 nm tuning range in a GaAlAs/GaAs CGT DFB laser.
