Abstract

Design of Fabry-Perot laser-based external cavity structures is presented with particular emphasis on linewidth and tunability. The important design parameters of this structure (ECSL-External Cavity Semiconductor Laser) which affect the linewidth are: optical feedback ratio, reflectivity of the laser facet nearer to the feedback component, frequency detuning of the optical feedback, external cavity length, and feedback bandwidth. We also studied the tuning charac-teristics of external cavity Fabry-Perot semiconductor lasers with strong feedback. It is shown that the gain change mechanism induced by the strong optical feedback in Fabry-Perot cavity is responsible for the spectral tuning. The Fabry-Perot resonator with external cavity can sup-port broad frequency detuning with varying threshold gain. The threshold gain decreases as the diffraction grating is tuned towards longer wavelengths.
