Thermal instability control by four wave mixing in optical microcavities

Summary form only given. The interplay between ultrafast and slow nonlinearities, like Kerr and thermo-optical nonlinearities, is well-known for generating bistability, self-pulsing and chaotic regimes in optical microcavities. These effects have been observed in different kinds of devices, such as doped silica glass optical microcavities with high refractive index [1], and numerical models have been investigated to provide a description of such dynamics, e.g. in semiconductor nanocavities [2-3]. Specifically, self-pulsing can be explored to generate all-optical stochastic sources, and it has been recently demonstrated with opto-mechanical nonlinearities [4]. In this framework, all-optical control of multistable or self-pulsing regions is highly desirable and it is usually achieved with an additional control signal.
