Ionization-induced asymmetric self-phase modulation and universal modulational instability in gas-filled hollow-core photonic crystal fibers
Ionization-induced asymmetric self-phase modulation universal modulational instability gas-filled hollow-core photonic crystal fibers Optics
2012/4/20
We study theoretically the propagation of relatively long pulses with ionizing intensities in a hollow-core photonic crystal fiber filled with a Raman-inactive gas. Due to photoionization, previously ...
Efficient and flexible generation of entangled qudits with cross-phase modulation
Efficient flexible generation entangled qudits cross-phase modulation
2013/7/3
In this paper, we provide a simple but powerful module to generate entangled qudits. This module, assisted with cross-Kerr nonlinearity, is flexible for generation of entangled qudits with arbitrary d...
Laser Beams with Spatio-Temporal Phase Modulation
Coherence control Partially coherent light Speckle smoothing
2009/6/8
This paper reviews a method of the irradiance profile smoothing on the high-power laser system. In the multi-beam laser irradiation geometry, the coherence control of laser beam is necessary to reduce...
Amplitude and phase modulation of time-energy entangled two-photon states
Amplitude phase modulation time-energy two-photon states
2010/4/9
We experimentally demonstrate amplitude and phase modulation of a time-energy entangled two-photon wave function. The entangled photons are produced by spontaneous parametric down-conversion, spectral...
