Memory-enhanced noiseless cross-phase modulation

Cross Phase Modulation and Four - Wave Mixing

Large conditional single-photon cross-phase modulation.

Deterministic optical quantum logic requires a nonlinear quantum process that alters the phase of a quantum optical state by π through interaction with only one photon. Here, we demonstrate a large conditional cross-phase modulation between a signal field, stored inside an atomic quantum memory, and a control photon that traverses a high-finesse optical cavity containing the atomic memory. This...

Spectral phase conjugation with cross-phase modulation compensation.

Spectral phase conjugation with short pump pulses in a third-order nonlinear material is analyzed in depth. It is shown that if signal amplification is considered, the conversion efficiency can be significantly higher than previously considered, while the spectral phase conjugation operation remains accurate. A novel method of compensating for cross-phase modulation, the main parasitic effect, ...

Optical Wavelength Converters Based on Cross Gain Modulation and Cross Phase Modulation in Soa

All optical wavelength conversion is demonstrated at 10 Gbit/s over a wavelength span of 10 nm without any bit loss by the use of Semiconductor Optical Amplifier (SOA) in a Mach-Zehnder configuration. These wavelength conversion architectures are implemented by using SOA cross-gain modulation (XGM) and cross-phase modulation (XPM) techniques. We have compared the results of both techniques on t...

Comparative analysis of self phase modulation (SPM) and cross phase modulation (CPM)

97 All Rights Reserved © 2012 IJARCSEE Abstract---Use of optical fiber communication is widely use due to its better bit rate and bandwidth and high carrier frequency with low power consumption. So, in this paper, we have analyzed non linear modulation techniques that are self phase modulation (SPM) and cross phase modulation (CPM) in an optical fiber system and discussed how these cause disper...
