15 صفحه اولQuantum Information Storage with Slow and Stopped Light
This essay describes the phenomena where the group velocity of light is reduced to ultraslow speeds, and even stopped in atomic gases. The coherent coupling of photons to atomic spin excitations in the gases through Electromagnetically Induced Transparency (EIT) is discussed, and experimental observation is presented as evidence of the phenomena with specific focus on the emergence of excited s...
متن کاملOn Instantaneous Amplitude and Phase of Signals - Signal Processing, IEEE Transactions on
In many questions of signal processing, it is important to use the concepts of instantaneous amplitude or phase of signals. This is especially the case in communication systems with amplitude or frequency modulation. These concepts are often introduced empirically. However, it is well known that the correct approach for this purpose is to use the concept of analytic signal. Starting from this p...
متن کاملStorage and retrieval of light pulses in atomic media with “slow” and “fast” light
We report experimental evidence that light storage, understood as the controlled release of a light pulse by an atomic sample dependent on the past presence of a writing pulse, is not restricted to small-group-velocity media but can also occur in a negative-group-velocity medium. We present a numerical modeling in close agreement with our observations and a simple physical picture applicable to...
متن کاملStorage-bit-rate product in slow-light optical buffers
Introduction: All-optical storage and signal processing are of intense interest for numerous applications, ranging from true-time delay for antenna remoting to all-optical convolution functions, all-optical signal regeneration, all-optical wavelength conversion, and all-optical buffers. The ability to control the optical group velocity over a wide range with high resolution is critical to enabl...
