Abstract

We demonstrate extremely efficient four-wave mixing with gains as high as 6 at microwatt pump powers in Rb vapor confined to a hollow-core photonic bandgap fiber.

Ultralow-Power Four-Wave Mixing with Rb in a Hollow-Core Photonic Band-Gap Fiber

We demonstrate extremely efficient four-wave mixing with gains greater than 100 at microwatt pump powers and signal-to-idler conversion of 50% in Rb vapor confined to a hollow-core photonic band-gap fiber. We present a theoretical model that demonstrates such efficiency is consistent with the dimensions of the fiber and the optical depths attained. This is, to our knowledge, the largest four-wave mixing gain observed at such low total pump powers and the first demonstrated example of four-wave mixing in an alkali-metal vapor system with a large (approximately 30 MHz) ground state decoherence rate.

Using light-induced atomic desorption, we generate an optically-dense Rb vapor on- demand inside a hollow-core photonic bandgap fiber for ultralow power nonlinear optical interactions.

All-optical modulation of four-wave mixing in an Rb-filled photonic bandgap fiber

Vivek Venkataraman, Pablo Londero, Amar R. Bhagwat +2 more

We demonstrate efficient all-optical modulation using Rb vapor confined to a hollow-core photonic bandgap fiber. The intensity of a signal field participating in the four-wave-mixing process is modulated using a weak switching field. We observe 3 dB of attenuation in the signal field with only 3600 photons of switching energy, corresponding to 23 photons per atomic cross section lambda(2)/(2pi). Modulation bandwidths as high as 300 MHz are observed.
