Four-wave-mixing stopped light in hot atomic rubidium vapour
Digital signal processing, holography, and quantum and classical information processing rely heavily upon recording the amplitude and phase of coherent optical signals. One method for achieving coherent information storage makes use of electromagnetically induced transparency. Storage is achieved by compressing the optical pulse using the steep dispersion of the electromagnetically induced tran...
متن کاملHigh efficiency coherent optical memory with warm rubidium vapour
By harnessing aspects of quantum mechanics, communication and information processing could be radically transformed. Promising forms of quantum information technology include optical quantum cryptographic systems and computing using photons for quantum logic operations. As with current information processing systems, some form of memory will be required. Quantum repeaters, which are required fo...
متن کاملEvaluation of the frequency stability of a VCSEL locked to a micro-fabricated Rubidium vapour cell [7720-63]
We present our evaluation of a compact laser system made of a 795 nm VCSEL locked to the Rubidium absorption line of a micro-fabricated absorption cell. The spectrum of the VCSEL was characterised, including its RIN, FM noise and line-width. We optimised the signal-to-noise ratio and determined the frequency shifts versus the cell temperature and the incident optical power. The frequency stabil...
متن کاملDouble-resonance spectroscopy in Rubidium vapour-cells for high performance and miniature atomic clocks
We report our studies on using microwave-optical double-resonance (DR) spectroscopy for a high-performance Rb vapour-cell atomic clock in view of future industrial applications. The clock physics package is very compact with a total volume of only 0.8 dm. It contains a recently in-house developed magnetron-type cavity and a Rb vapour cell. A homedmade frequency-stabilized laser system with an i...
متن کاملA heated vapor cell unit for DAVLL in atomic rubidium
The design and performance of a compact heated vapor cell unit for realizing a dichroic atomic vapor laser lock (DAVLL) for the D2 transitions in atomic rubidium is described. A 5 cm-long vapor cell is placed in a double-solenoid arrangement to produce the required magnetic field; the heat from the solenoid is used to increase the vapor 1 ar X iv :0 71 1. 09 11 v1 [ ph ys ic s. at om -p h] 6 N ...
