Design and Simulation of a Directly Frequency-Modulated DFB Laser
Abstract
In this work we propose a simple approach to realize the direct frequency modulation of a semiconductor distributed feedback (DFB) laser. The directly frequency-modulated DFB laser (DFL) is biased by a direct current (DC) on a normal electrode along the laser cavity to define the output power. The signal current is applied on an extra short electrode placed in the center section of the DFB laser, isolated from the DC electrode. The varying of …
