A simple approach to the formation of a Hamiltonian matrix for some Schrodinger equations describing the molecules with large amplitude motions has been proposed. The algorithm involving one or severa...
A phase preserving limiter based on injection locking in semiconductor lasers is experimentally investigated for 10Gb/s phase encoded signals. The proposed scheme exhibits significant amplitude noise ...
We present results of a polarization diverse LCoS wavelength processor. Applications include impairment simulation of broadband, channelized and intra-band PMD and PDL for detailed experimental sensit...
4 bps/Hz 40 Gb/s carrierless amplitude and phase (CAP) modulation is investigated for next-generation datacommunication links. The 40 Gb/s link achieves double the length of a conventional NRZ scheme,...
160Gb/s all-optical binary-to-quaternary amplitude shift keying format conversion is carried out in nonlinear optical fiber. This scheme, which also acts as a 2-bit digital-to-analog convertor, has be...
Microcavity Saturable absorber is used for phase-preserving amplitude regeneration of RZ-DQPSK signals. The regenerator is assessed in a 28 Gbaud recirculating loop showing system tolerance to nonline...
We introduce a novel input-idler-free non-degenerate phase sensitive amplifier (PSA) configuration and use it for simultaneous phase and amplitude regeneration of quadrature phase shift keyed (QPSK) s...
Successful transmission of up to 300 Mbps over a 50 m long POF link using a commercially available Fast Ethernet capable RC-LED is presented. Carrierless Amplitude Phase modulation was used with 16- a...
We propose a coded N-dimensional pulse-amplitude modulation (ND-PAM) suitable for ultra-high-speed serial optical transport. The polarization-multiplexed-ND-PAM significantly outperforms corresponding...
We report experimental results on an optical beamformer capable of independent amplitude and phase control of RF signals fed to an antenna array. We investigate its performance for beam direction adju...
We experimentally evaluate a novel all-optical phase-preserving amplitude regeneration technique for RZ-DPSK signals using saturable absorber. The device’s capacity for amplitude noise reduction, henc...
Design and fiber optimization in NOLM-type regenerators allow for a substantial decrease in excess noise originating from Rayleigh backscattering. Cascaded operation of up to 20 phase-preserving limit...
Simultaneous noise suppression of time-interleaved three-wavelength optical signals using saturation of four-wave mixing in a fiber is reported. Nonlinear phase noise reduction of three-wavelength DPS...
Catering to the current interest in high-order modulation formats, this paper discusses possible transmitter configurations and receiver concepts. Moreover, the major trends in system performance are ...
Experimental results obtained on 10 Gb/s RZ-DPSK transmission in a recirculating fiber-loop setup show that nonlinear amplifying loop mirrors can efficiently enhance system performance. Main limiting ...
