Lecture by Uriel Levy

Recent advancements in on chip enhanced light-vapor interactions at the nanoscale

Abstract: In this talk I will describe our recent results related to the chip scale integration of atomic vapors on a chip. Following a brief introduction and discussion regarding the platform of atomic cladded waveguides (ACWG) and the technology, I will move on to present the observations of chip scale linear spectroscopy, nonlinear interactions, light shift effects, cavity enhanced optical switching, and strong coupling (Autler Townes). Next, I will describe the plasmonic counterpart platform, with results showing controlled dispersion, all optical switching and Fano interference. Finally, I will discuss the effect of applying magnetic fields.
