Optical similaritons in nonlinear waveguides.

چکیده
We discover analytically an extensive family of optical similaritons, propagating inside graded-index nonlinear waveguide amplifiers. We show that there exists a one-to-one correspondence between these novel similaritons and standard solitons of the homogeneous nonlinear Schrödinger equation. We demonstrate that for certain inhomogeneity and gain profiles, the newly discovered similaritons turn into solitons over sufficiently long propagation distances.

Optical pulse compression based on nonlinear silicon waveguides and chirped Bragg gratings
Due to the growing demand for higher bandwidth, employing optical devices instead of electronic devices in data transmission systems has attracted much attention in recent years. Optical switches, modulators and wavelength converters are a few examples of the required optical devices. CMOS compatible fabrication of these devices, leads to much more growing of this technology. Optical pulse comp...
متن کاملA novel design for all-optical NAND/NOR/XOR gates based on nonlinear directional coupler
In this paper a novel all-optical logic NAND, NOR and XOR gate based on nonlinear directional coupler theory is demonstrated. We use the identical structure which contains three waveguides, for designing these gates; the only difference however, is the power of inputs light beam. In other words, while a beam with 4 W/μm in power considered as logical one, the output is NAND gate and if a beam w...

متن کاملInfluence of the pumping configuration on the generation of optical similaritons in optical fibers
The impact of forward and backward amplification schemes on the generation of optical similaritons has been numerically and experimentally investigated around 1550 nm using a fiber based Raman amplifier. The pumping configuration does not affect the similariton nature of the output pulse, but it significantly influences the characteristics of the pulse. Shorter and higher peak-power similariton...
متن کاملNonlinear interaction of two or more similaritons in loss- and dispersion-managed fibers
We study the nonlinear interaction of two or more fundamental and higher-order similaritons. In particular, we consider the bright similaritons, propagating in nonlinear fibers whose gain–loss and anomalous dispersion vary along the fiber. We first focus on the situation such that the similaritons propagate with the same velocity but are spaced closely enough to overlap. Similar to the soliton ...
