Fabry-Pérot laser diode spectrum switching by controllable self-injection locking to a high-quality-factor optical microresonator

Abstract

We propose a technique for automatic search and identification of possible generation regimes of a commercial multimode Fabry-Pérot laser diode self-injection locked to a high-quality-factor whispering gallery mode microresonator. Such a technique provides the potential for controllable switching between regimes with different wavelengths and with a specific number of lasing modes.
