Abstract :
The wavelength tuning characteristics of two-section gain-levered Fabry-Perot quantum well laser diodes with unequal (asymmetric) facet reflectivities are investigated theoretically, taking into account the longitudinal variations of carrier and photon densities. It is demonstrated that, under appropriate biasing conditions, enhancement of wavelength tunability can be achieved in asymmetric Fabry-Perot laser diodes
