Space-variant incoherent optical processing using color
Incoherent optical processing techniques offer superior noise immunity, among other benefits, over coherent optical processing techniques. However, the complex amplitude linearity exhibited by coherent optical systems that provides a natural means for performing operations on complex functions, is …

Modal Optical Studies of Multi-Moded Ultra-Low-Noise Detectors in Far-Infrared
… for modelling the behaviour of partially coherent optical systems and multi-mode detectors. The numerical simulations were carried out for the ultra-low-noise Transition Edge Sensors (TESs) being proposed for use on the SAFARI instrument on the cooled aperture infrared space telescope …

Multilevel Nyquist-WDM Ultra-Long-Haul Coherent Optical Transmission Systems
… a proper capacity upgrades plan, with new optical links deployment, has required for back-bone optical networks in order to avoid possible networks congestions. Such effect has theoretically forecast as probable in actual networks within next few tenths years, particularly in US if some …

Adaptive polarization mode dispersion equalizers for coherent optical communications systems
… (PMD) arises as a result of the birefringence in optical fibers, due to inherent asymmetries and deformities from external stresses. The spectral components of the input optical pulse propagate with different group velocities. Consequently, pulse duration increases leading to intersymbol …
