Optical Nanofibers

Promotional image for talk: Elements of a successful scientific talk

Speaker(s): Luis A. Orozco

Nanofibers are a versatile platform for applied and fundamental studies. I will聽present our work starting with the production and characterization of the fibers. Then I聽will show that Rayleigh scattering from modes on the nanofiber gives information about聽the diameter with sub-micron resolution. We are using nanofibers for quantum optics聽and quantum information studies. We use the evanescent fields around an optical聽nanofiber (500 nm diameter) with 99.95% transmission to form an atom trap suitable for聽operation in cryogenic environments. We are developing methods to measure: the聽temperature of Rb atoms around the fiber, and the coupling of the Rb atoms into the聽mode of the fiber. Future plans include the study of the dynamics of a one dimensional聽array of atoms under different interaction conditions.

Work done in collaboration with J. A. Groover, P. A. Solano, S. L Rolston, F. K.聽Fatemi and G. Beadie. This work is supported by NSF though the PFC@JQI, the聽Atomtronics MURI, ONR, and DARPA.

Colloquium

Junior and senior physics majors attend our biweekly colloquium series, held on Tuesday afternoons at 4:30 p.m. in Shanahan B460. The talks are open to all students and to the public, and are frequently attended by scientists from the other Claremont Colleges, Cal Poly Pomona, and others. The series features speakers from a broad range of institutions and fields of physics.
