Modelling of linearly chirped fiber Bragg gratings by the method of single expression
Springer Science and Business Media LLC - Tập 34 - Trang 481-492 - 2002
H.V. Baghdasaryan, T.M. Knyazyan
To model chirped fiber Bragg gratings (FBGs) for dispersion compensation in optical fibers a novel method of single expression (MSE) is used. The reformulation of Helmholtz's equation in the MSE to the full set of first-order differential equations leads to dealing with the electric field amplitude, its derivative, power flow density and phase distributions in any aperiodic media. The phase deriva... hiện toàn bộ

Minimization of the pulse's timing jitter in a dispersion-compensated WDM system
Springer Science and Business Media LLC - Tập 36 - Trang 349-366 - 2004
Ofir Aharon, Boris A. Malomed, Y.B. Band, U. Mahlab
We address the problem of the collision-induced crosstalk between pulses in a dispersion-compensated WDM system composed of a periodic array of cells that include two or three fiber segments. Both the cross- and self-phase-modulation nonlinearities are taken into account. A semi-analytical approximation and direct simulations are used to calculate the frequency shift (FS) of colliding pulses, and ... hiện toàn bộ
Laser-induced behavior of BK7 mirror in a compound resonator on watt level DUV laser
Springer Science and Business Media LLC - Tập 47 - Trang 2181-2188 - 2014
Fengjiang Zhuang, Ge Zhang, Siqi Zhu, Bingxuan Li
We experimentally present an acousto-optic Q-switched, side-pumped laser generating the watt-level deep-ultraviolet (DUV) output at 266 nm. A quasi-enhanced cavity, containing a BBO crystal as the fourth harmonic generator, was employed in the compact DUV laser system. A DUV laser with the average power of 1.08 W was achieved after careful alignment of the resonator. Our experimental results demon... hiện toàn bộ
A cascaded FBG scheme based OQPSK/DPSK modulation for chromatic dispersion compensation
Springer Science and Business Media LLC - Tập 54 Số 7 - 2022
Fathy M. Mustafa, Sayed A. Zaky, Ashraf A. M. Khalaf, Moustafa H. Aly
AbstractThe aim of this study is to present a proposed chromatic dispersion compensation model for single mode optical fiber. The proposed model consists of 4-stages of cascaded identical linear chirped fiber Bragg grating (CFBG) in post-compensation connection scheme. It is based on differential phase shift keying modulation format. To evaluate the performance of the proposed model, a comparative... hiện toàn bộ
Optical fibre excitation by partially coherent sources
Springer Science and Business Media LLC - Tập 8 - Trang 545-556 - 1976
D. J. Carpenter, C. Pask
Sources for optical fibre excitation have previously been assumed to be either totally coherent or incoherent. This paper formulates the modal excitation problem for partially coherent sources. The modal excitation coefficients are given in terms of the source complex degree of coherence and numerical results and simple analytical expressions appropriate to multimode step index fibres are presente... hiện toàn bộ

Performance optimization of RSOA based mm-wave radio-over-fibre access network
Springer Science and Business Media LLC - Tập 53 - Trang 1-14 - 2021
Eszter Udvary
In this paper, a Reflective Semiconductor Optical Amplifier based, Radio-over-Fibre access network configuration has been proposed to feed future millimeter-wave radio systems. The system architecture combines several approaches to overcome the challenges of millimeter-wave signal transmission. Reflective semiconductor optical amplifier modulator realizes a colorless and relatively cost-effective ... hiện toàn bộ

All solid quasi-single material supermode microstructure fiber with flattened dispersion and single mode transmission
Springer Science and Business Media LLC - Tập 50 - Trang 1-11 - 2018
Wei Wang, Shi Qiu, Tianxu Lin, Haidong Xu, Fanchao Meng, Ying Han, Yuefeng Qi, Lantian Hou
An all solid quasi-single material microstructure fiber (AS-QSM-MSF) with flattened dispersion and single mode transmission is presented in this paper. Besides microstructured cladding, six-core configuration is also employed to incorporate mode coupling mechanism into light transmission control in our proposed fiber. By doing this, flattened dispersion in the range of − 1.03–0.75 ps/(nm km) can b... hiện toàn bộ
