Robust optimization of adiabatic tapers for coupling to slow-light photonic-crystal waveguides
Tapered structure coupling photonic crystal waveguides candles nano
2015/8/7
We investigate the design of taper structures for coupling to slow-light modes of various photonic-crystal waveguides while taking into account parameter uncertainties inherent in practical fabricatio...
Controllable ultra-broadband slow light in a warm Rubidium vapor
Controllable ultra-broadband slow light Rubidium vapor Optics
2011/8/18
Abstract: We study ultra-broadband slow light in a warm Rubidium vapor cell. By working between the D1 and D2 transitions, we find a several-nm window centered at 788.4 nm in which the group index is ...
Observation of slow light in the noise spectrum of a vertical external cavity surface emitting laser
Observation slow light noise spectrum emitting laser
2010/11/11
The role of coherent population oscillations is evidenced in the noise spectrum of an ultra-low noise lasers. This effect is isolated in the intensity noise spectrum of an optimized single-frequency v...

Elimination Diffraction of Arbitrary Images Slow Light
2010/4/12
We present a scheme for eliminating the optical diffraction of slow-light in a thermal atomic medium of electromagnetically induced transparency. Nondiffraction is achieved for an arbitrary paraxial i...
Realistic theory of electromagnetically-induced transparency and slow light in a hot vapor of atoms undergoing collisions
Realistic theory electromagnetically-induced transparency slow light a hot vapor of atoms undergoing collisions
2010/4/9
We present a realistic theoretical treatment of a three-level $\Lambda$ system in a hot atomic vapor interacting with a coupling and a probe field of arbitrary strengths, leading to electromagneticall...
Slow light of an amplitude modulated Gaussian pulse in electromagnetically induced transparency medium
amplitude modulated Gaussian pulse electromagnetically transparency medium
2010/4/9
The slow light effects of an amplitude modulated Gaussian (AMG) pulse in a cesium atomic vapor are presented. In a single-$\Lambda$ type electromagnetically induced transparency (EIT) medium, more sev...
Efficient all-optical switching using slow light within a hollow fiber
all-optical switching slow light a hollow fiber
2010/4/7
We demonstrate a fiber-optical switch that is activated at tiny energies corresponding to few hundred optical photons per pulse. This is achieved by simultaneously confining both photons and a small l...
