Low-Light-Level Optical Interactions with Rubidium Vapor in a Photonic Bandgap Fiber

Saikat Ghosh, Amar R. Bhagwat, C. Kyle Renshaw +3

We show that a Rubidium vapor can be produced within the core of a photonic band-gap fiber yielding an optical depth in excess of 2000. Our technique for producing the vapor is bas…
