Cross-phase modulation and induced focusing due to optical nonlinearities in optical fibers and bulk materials
نویسندگان
چکیده
Cross-phase modulation (XPM) and induced focusing occur when copropagating ultrafast pulses interact in a nonlinear medium. XPM and induced focusing are investigated as new techniques to control the spectral, temporal, and spatial properties of ultrafast pulses with femtosecond time response. In this paper we review our most recent measurements on (1) induced spectral broadening in BK7 glass, (2) induced frequency shift of copropagating pulses in optical fibers, (3) XPM-stimulated Raman scattering in optical fibers, (4) XPM secondharmonic generation in ZnSe crystals, and (5) induced focusing of Raman pulses in optical fibers.

Helical versus Fundamental Solitons in Optical Fibers
We consider solitons in a nonlinear optical fiber with a single polarization in a region of parameters where it carries exactly two distinct modes, viz., the fundamental one and the first-order helical mode. From the viewpoint of applications to dense-WDM communication systems, this opens way to double the number of channels carried by the fiber. Aside from that, experimental observation of hel...

متن کاملPhase gate with a four-level inverted-Y system
An all-optical quantum computation has been proposed but a realization of two-qubit quantum gates, which are required for universal quantum computation, is not so straightforward due to lack of significant photon-photon interaction 1 . Many proposals have come up in recent years for efficiently implementing all-optical quantum computation. The linear optics quantum computation scheme is based o...
متن کاملEffect of Nonlinear Phase Variation in Optical Millimetre Wave Radio over Fibre Systems
In this paper, we propose an optical millimetre wave radio-over-fibre (mm-wave RoF) system that uses a dual drive Mach Zehnder modulator (DD-MZM), which is biased at the maximum transmission biasing point, to generate an optical double sideband-suppressed carrier. The input to the DD-MZM are binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), 8-phase shift keying (8-PSK) and...
