Abstract
Nearly degenerate four-wave mixing in two-section single-mode laser diodes with unequal (asymmetric) facet reflectivities is studied theoretically. It is demonstrated that, under appropriate biasing conditions, the device exhibits a uniform phase-conjugate reflectivity over a frequency detuning range of more than 10 GHz. We can simultaneously achieve enhancement of the four-wave-mixing bandwidth and efficiency by injecting the probe signal at and deriving the conjugate output from the low-reflectivity facet of an asymmetric two-section laser diode.
