Ryan Behunin DESCRIPTION:Dr. Ryan BehuninDepartment of Applied Physics & Materials Scie nceCenter for Materials Interfaces in Research & ApplicationsNorthern Ari zona University\n\n\nAbstract:Owing to their highly coherent emission and compact form factor\, stimulated Brillouin scattering (SBS) lasers have been recognized as an attractive solution for applications such as portab le atomic clocks\, precision sensors\, coherent microwave synthesis and e nergy-efficient approaches to coherent communications. While the SBS emis sion can be very narrow band\,  noise inherent within dielectric material s leads to drift in the Brillouin laser frequency posing vexing challenge s for high-end applications requiring ultra-stable emission. In this talk \, I’ll discuss our efforts to develop unified models to understand Brill ouin laser physics that incorporate the dominant sources of noise. The ph ysics and applications of Brillouin scattering will be introduced\, and o ur modeling approach will be discussed. Our predictions will be compared with data from an integrated photonic SBS laser\, showing that the thermo refractive effect plays a critical role in the laser’s frequency stabilit y.\n\n\nThis seminar will be held exclusively on Zoom (955 5209 1021).
