Paper Abstract

A simple optical rate equation for a distributed feedback laser is derived following an analytical procedure that is based on transforming a known integral equation into an equivalent differential equation. Using this equation to model fluctuations in the phase and photon number, when supplemented with a rate equation for the carrier number expressions for the relaxation oscillation characteristics and linewidth are derived. We find that in a simple distributed feedback structure the relation for the relaxation oscillation frequency is identical to that of the Fabry-Perot laser. An effective linewidth-broadening factor is predicted showing strong dependence on longitudinal hole- burning. Power re-broadening of the linewidth and a nearly vanishing power-independent component are predicted. Finally, rate equations for injection-locking are derived, and a symmetric dynamically stable locking band predicted.
