1. Phase-sensitive amplifiers for nonlinearity impairment mitigation in optical fiber transmission links
Sammanfattning : The fundamental limitations in fiber-optic communication are caused by optical amplifier noise and the nonlinear response of the optical fibers. The quantum-limited noise figure of erbium-doped fiber amplifiers (EDFAs) or any phase-insensitive amplifier is 3 dB. LÄS MER
2. Nonlinearity mitigation in phase-sensitively amplified optical transmission links
Sammanfattning : The fundamental limitations in fiber-optic communication are caused by optical amplifier noise and the nonlinear response of the optical fibers. The quantum-limited noise figure of erbium-doped fiber amplifier (EDFA) or any phase-insensitive amplifier is 3 dB. LÄS MER
3. All-optical nonlinearity mitigation in fiber-optic communications
Sammanfattning : The two main factors limiting the data throughput in modern fiber-optic communication links are the noise added by amplifiers and the nonlinear response of the optical fiber due to the Kerr effect. Today there are communication systems operating remarkably close to the limits set by these two factors. LÄS MER
4. Phase-Sensitive Fiber Optic Parametric Amplifier and Their Applications in Optical Communications
Sammanfattning : This thesis deals with experimental and theoretical aspects of the phase-sensitive fiber optic parametric amplifier (FOPA) and their applications. FOPAs can be oper- ated as both phase-insensitive and phase-sensitive amplifiers (PSAs), with the latter requiring phase-locked input waves, which, until recently, has limited their practi- cal use.

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