2. 11. Characterization and Applications of Vector Phase-Sensitive Amplifiers

   Author : Abel Lorences Riesgo; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; parametric amplification; phase-sensitive amplification; fiber nonlinearities; four-wave mixing; all-optical processing;

   Abstract : This work is devoted to the characterization of vector phase-sensitive amplifiers and processors. A detailed analysis of degenerate vector phase-sensitive amplifier (PSA) is performed.The gain and phase-sensitive extinction ratio are theoretically analyzed using three-wave theory. READ MORE

4. 12. Fiber-based all-optical sampling for ultrafast waveform monitoring

   Author : Mathias Westlund; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polarization independent; waveform monitoring; software synchronization; four-wave mixing; all-optical sampling;

   Abstract : Digital sampling is a technique to visualize a time-varying waveform by capturing quasi-instantaneous snapshots of a signal via a sampling gate. The gate is opened and closed by narrow pulses in a pulse train having a well defined repetitive behaviour such that all parts of the waveform are measured. READ MORE

5. 13. Signal Characterization in Optical Networks

   Author : Mats Sköld; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The thesis presents and demonstrates methods to characterize high-speed (>10 Gbaud) signals in fiber optic communication systems and networks, including acquisition of the optical signal intensity, amplitude, phase and polarization. These quantities are necessary for the analysis of system performance, both in research and development stages, as well as for monitoring and management of operational systems. READ MORE

6. 14. Modeling and Tracking of Stochastic Polarization Drifts in Fiber-Optic Systems

   Author : Cristian Bogdan Czegledi; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : In the past decade, accessing information has become easier than ever, leading to a rapid growth in popularity of social media, online gaming, and multimedia broadcast systems. These and other services put pressure on the Internet service providers to support high-speed Internet connections and motivate the need for faster communication systems. READ MORE
