Abstract
Optical microcavities provide opportunities to explore nonlinear effects and enable classic and quantum applications. This work investigates the manipulation of rare-earth-ion emission through nonlinear-mode oscillation in an erbium-doped thin-film lithium niobate microdisk cavity and demonstrates the changed laser performance. A pulsed transmission was generated with a detuned laser injected into the cavity. If the injected laser meets the pump band of the erbium ions, the output communication-band laser is also pulsed. The pulse's repetition rate and duration are changed with different detuned pump wavelengths and powers. All-optical temporal control of the emitter-cavity interaction paves the way to manipulation of quantum states with solid-state devices.
