1. 1. Towards Practical Implementation of Phase-Sensitive Amplifier Based Transmission Systems

   Författare :Samuel L I Olsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase-sensitive amplification; four-wave mixing; nonlinear optical signal processing; optical injection locking; fiber nonlinearities; fiber optic parametric amplification;

   Sammanfattning : All commercially available optical amplifiers are so-called phase-insensitive amplifiers (PIAs) which degrade the signal-to-noise ratio (SNR) through the amplification process. This kind of amplifier has a quantum limited noise figure (NF) of 3 dB. LÄS MER

3. 2. Optical Transmission Systems Based on Phase-Sensitive Amplifiers

   Författare :Samuel L I Olsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical injection locking; fiber nonlinearities; optical fiber communication; fiber nonlinearity mitigation; four-wave mixing; fiber optic parametric amplification; low-noise amplification; phase-sensitive amplification; fibre optics;

   Sammanfattning : The capacity and reach of today's long-haul fiber optical communication systems is limited by amplifier noise and fiber nonlinearities. Conventional, phase-insensitiveamplifiers (PIAs), have a quantum limited noise figure (NF) of 3 dB at high gain, meaning that with a shot-noise limited input signal the signal-to-noise ratio (SNR)is degraded by at least 3 dB.
