Effect of input phase modulation to a phase-sensitive optical amplifier

Phase-to-phase and phase-to-amplitude transfer characteristics of a nondegenerate-idler phase-sensitive amplifier.

For the first time to our knowledge, the phase-to-phase and phase-to-amplitude transfer functions of a nondegenerate-idler phase-sensitive fiber optic parametric amplifier are experimentally measured. Additionally, analytically and numerically obtained transfer curves show excellent agreement with the experimental curves. The experimental results were obtained by imposing a linear phase modulat...

Design, Analysis and Simulation of a Linear Phase Distributed Amplifier

In this paper a new method for the design of a linear phase distributed amplifier in 180nm CMOS technology is presented. The method is based on analogy between transversal filters and distributed amplifiers topologies. In the proposed method the linearity of the phase at frequency range of 0-50 GHz is obtained by using proper weighting factors for each gain stage in cascaded amplifier topology....

Study of Phase Sensitive Amplifier (psa) Characteristic for 80 Gbit/s Dpsk Data Input Signal

Simulation of phase sensitive amplifier (PSA) of differential phase shift keying (DPSK) data signal in dual pump is presented. The PSA is designed and simulated using OptiSystem software. A dual pump PSA based on cascaded fiber optic parametric amplifier (FOPA) of 80Gbit/s DPSK data signal is investigated in detail on its gain and noise figure. Results show that PSA has higher gain and lower no...

QPSK 3R regenerator using a phase sensitive amplifier.

A black box phase sensitive amplifier based 3R regeneration scheme is proposed for non-return to zero quadrature phase shift keyed formatted signals. Performance improvements of more than 2 dB are achieved at the presence of input phase distortion.
