Coherent analysis of quantum optical sideband modes.
We demonstrate a device that allows for the coherent analysis of a pair of optical frequency sidebands in an arbitrary basis. We show that our device is quantum noise limited, and hence applications for this scheme may be found in discrete and continuous variable optical quantum information experiments.
متن کاملPerformance of Coherent Optical Communication Systems With Hybrid Fiber Spans
We theoretically study the performance of coherent optical communication systems using quasi-single-mode fiber in the beginning of each span, to reduce the bulk of nonlinearities, followed by single-mode fiber, to limit multipath interference penalty within acceptable levels. Introduction Quasi-single-mode (QSM) fibers exhibit very large effective areas that result in a dramatic reduction of fi...
متن کاملPerformance Analysis of Unipolar Code in Different Phase Modulations of Coherent Optical CDMA
binary phase-shift keying (BPSK) format is deployed where the phase is modulated by either an external phase-modulator or injection-locking methods. The phase limitation and the performance for both phase-modulations including multiple access interferences (MAI) in a shot-noise limited regime are studied and moderate penalty associated with the limited phase excursion is revealed.
متن کاملPerformance analysis of partially coherent SSD systems
The performance analysis of a system employing co-ordinate interleaving and constellation rotation, over Nakagami-m fading channels, in the presence of phase noise as well as additive white Gaussian noise, is presented. An upper bound for the average probability of bit error for M-ary phase shift keying is derived. It is shown that the derived upper bound is tight for high signal-to-noise ratio...
متن کاملPERFORMANCE ANALYSIS OF DISPERSION COMPENSATION TECHNIQUES IN A 100 Gbps COHERENT-OPTICAL SYSTEM
AbstractLong haul transmission links evolve with the advent of new multiplexing and modulation schemes. We propose a new approach of dispersion compensated coherent optical orthogonal frequency division multiplexing scheme which is combined with quadrature amplitude modulation to double the data rate and spectral efficiency as transmitted in an optical OFDM system. Quadrature amplitude modulati...
