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 ...
Modulation instability in nonlinear metamaterials induced by cubic-quintic nonlinearities and higher order dispersive effects
Modulation instability nonlinear metamaterials cubic-quintic nonlinearities higher order dispersive effects Optics
2012/4/20
We have investigated modulation instability in metamaterials (MM) with both cubic and quintic nonlinearities, based on a model appropriate for pulse propagation in MMs with cubic-quintic nonlinearitie...

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...
A Novel Direct Detection Microwave Photonic Vector Modulation Scheme for Radio-Over-Fiber System
2011/11/22
This letter demonstrates the feasibility of a novel direct detection microwave photonic vector modulation scheme for the radio-over-fiber (RoF) system. Unlike the traditional double-sideband with opti...
Solitons in thermal media with periodic modulation of linear refractive index
thermal media periodic modulation linear refractive index
2011/9/6
We address the existence and the properties of solitons in thermal media with periodic distribution of two different linear refractive indices. Many kinds of
solitons in such optical lattices, includ...
Amplitude Modulation Effects in Cardiac Signals
Amplitude Modulation Effects Cardiac Signals
2010/11/16
A subject's heart beat can be nearly invisible in a spectrum, when that spectrum is generated using conventional methods of Fourier analysis. The phenomenon has been observed in records of both elect...
Light tunneling inhibition in array of couplers with combined longitudinal modulation of refractive index
Light tunneling inhibition combined longitudinal modulation refractive index
2010/4/7
We consider light tunneling inhibition in periodic array of optical couplers due to the specially designed longitudinal and transverse modulation of the refractive index. We show that local out-of-pha...
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...
