Study of All-Optical Wavelength Conversion and Regeneration Subsystems for use in Wavelength Division Multiplexing (WDM) Telecommunication Networks
In this thesis, we study all-optical processing techniques based on non-linear semiconductor optical amplifiers for the functionalities of second and third generation optical networks. In particular, devices for all-optical wavelength conversion with regenerative properties have been investigated. The configurations under investigation are based on the non-linear four-wave mixing process which ...
متن کاملQuadrature Amplitude Modulation All Optical Orthogonal Frequency Division Multiplexing-dense Wavelength Division Multiplexing-optical Wireless Communication System under Different Weather Conditions
This paper proposes an analytical model for evaluating the performance of dense wavelength division multiplexing (DWDM) for all optical orthogonal frequency division multiplexing (AO-OFDM) optical wireless channel. The investigated performance for proposed system is evaluated for the parameters bit error rate (BER) and Q factor .The constellation diagrams, and bit error rate (BER) of the recei...
متن کاملWavelength division multiplexing of chaotic secure and fiber-optic communications.
Wavelength division multiplexing (WDM) transmission of chaotic optical communication (COC) and conventional fiber-optic communication (CFOC) is numerically confirmed and analyzed. For an 80-km-long two-channel communication system, a 1-Gb/s secure message in COC channel and 10-Gb/s digital signal in CFOC channel are simultaneously achieved with 100 GHz channel spacing. Our numerical simulations...
متن کاملPhotonic Crystal Devices for Wavelength-Division-Multiplexing and Optical Modulation
This paper reviews photonic crystal (PC) based demultiplexers, and briefly reports our latest experimental achievement in ultra-compact, power-efficient silicon photonic crystal waveguide (PCW) modulators. We review the modeling techniques for photonic crystal superprism devices, which utilize anomalous refraction on a photonic crystal surface for wavelength demultiplexing. The finite differenc...
متن کاملWavelength and Space Code Division Multiplexing in Optical Tomography
Optical Tomography aims at reconstructing one or more spatially variable coefficients in a volume from measurements of propagation of near infrared light fluxes at its surface. The propagation of near infrared photons in biological media has a diffusive nature, as photons are absorbed and massively scattered by tissues, and coefficients are reconstructed by post-processing algorithms. Time reso...
