چکیده
Title of Thesis: POLARIZATION-INSENSITIVE TECHNIQUES FOR OPTICAL SIGNAL PROCESSING Degree candidate: Reza Salem Degree and year: Doctor of Philosophy, 2006 Thesis directed by: Professor Thomas E. Murphy Department of Electrical and Computer Engineering This thesis investigates polarization-insensitive methods for optical signal processing. Two signal processing techniques are studied: clock recovery based on two-photon absorption in silicon and demultiplexing based on cross-phase modulation in highly nonlinear fiber. The clock recovery system is tested at an 80 Gb/s data rate for both back-to-back and transmission experiments. The demultiplexer is tested at a 160 Gb/s data rate in a backto-back experiment. We experimentally demonstrate methods for eliminating polarization dependence in both systems. Our experimental results are confirmed by theoretical and numerical analysis.

متن کاملA Full-Duplex, Dual-Polarization 10Gbps Radio over Fiber system with wavelength reuse for upstream signal
This study presents a full-duplex Radio-over-Fiber (RoF) system providing the users' wireless access with a bit rate of 10 Gbps over 40 GHz radio carrier. This system can be used in a centralized radio access network (C-RAN) architecture because we provide a fully analog front haul link between central station and base station. We can consider it as infrastructure between remote radio heads (RR...
متن کاملThe Application of SOA in All-optical Wavelength Conversion and ROF System
Wavelength conversion has been suggested as one of the key functions for wavelengthdivision-multiplexing (WDM) optical networks and photonic switch blocks. Several methods, such as a self-phase modulation (SPM), a cross-gain modulation (XGM), and crossphase modulation (XPM), can be used to realize all optical wavelength conversion (AOWC) [1-29]. However, four-wave mixing (FWM) based on nonlinea...

متن کاملPolarization-insensitive optical spectral inversion without frequency shift based on four-wave mixing in semiconductor optical amplifiers
Two schemes for polarization-insensitive optical spectral inversion without frequency shift based on four-wave mixing are proposed, both utilizing a conventional semiconductor optical amplifier (SOA) and two pump waves. The significant advantages of the configurations include their simplicity, effective suppression of the signal and one of the pump waves and a reduction in the noise associated ...
