摘要： Techniques are provided to optomechanically couple light to a crystal structure, thereby producing stable, coherent bulk acoustic modes within the structure. In some embodiments, a resonator may comprise a plano-convex crystal structure to which pump light may be applied. The pump light may transfer energy to acoustic phonon modes of the crystal structure so as to create acoustic phonon modes with a coherence length greater than a length of the crystal structure. High frequency and high quality factor resonators may thereby be produced and operated.

摘要： Techniques for producing a Brillouin laser are provided. According to some aspects, techniques are based on forward Brillouin scattering and a multimode acousto-optic waveguide in which light is scattered between optical modes of the waveguide via the Brillouin scattering. This process may transfer energy from a waveguide mode of pump light to a waveguide mode of Stokes light. This process may be referred to herein as Stimulated Inter-Modal Brillouin Scattering (SIMS). Since SIMS is based on forward Brillouin scattering, laser (Stokes) light may be output in a different direction than back toward the input pump light, and as such there is no need for a circulator or other non-reciprocal device to protect the pump light as in conventional devices.
