Optimizing Ampliier Placements in a Multi-wavelength Optical Lan/man: the Equally-powered-wavelengths Case
Wavelength-division multiplexing (WDM) provides the ability to utilize the enormous band-width ooered by optical networks, using today's electronics. WDM-based optical networks employing passive-star couplers have been proposed for deployment in local and metropolitan areas. Optical ampliication is often required in such networks to compensate for the signal attenuation along the ber links and ...
متن کاملOptimizing Ampliier Placements in a Multi-wavelength Optical Lan/man: the Unequally-powered-wavelengths Case
Optical networks based on passive star couplers and employing wavelength-division multi-plexing (WDM) have been proposed for deployment in local and metropolitan areas. These networks suuer from splitting, coupling, and attenuation losses. Since there is an upper bound on transmitter power and a lower bound on receiver sensitivity, optical ampliiers are usually required to compensate for the po...
متن کاملOptical frequency comb metrology from infrared to extreme ultraviolet wavelengths
We report on frequency comb generation at 1.5 μm by injection of a CW laser in a hybridly1 mode-locked InAs/InP two-section quantum-dot laser (HMLQDL). The generated comb has > 60 modes spaced by ∼ 4.5 GHz and a -20 dBc width of> 100 GHz (23modes) at> 30 dB signal to background ratio. Comb generation was observed with the CW laser (red) detuned more than 20 nm outside the HMLQDL spectrum, spann...
متن کاملOptical Network Architectures for Dynamic Reconfiguration of Full Duplex, Multi- wavelength, Radio-over-Fibre
In recent years there have been rapid advances in the techniques to generate and transport radio signals over optical fibre, however very little has been done to date to develop the concept of a full duplex, multi-wavelength, radio -over-fibre network architecture that intrinsically supports and facilitates the dynamic reconfiguration of the wireless network. Recently the development of suitabl...
متن کاملStudies of Neutron Stars at Optical / IR Wavelengths
In the last years, optical studies of Isolated Neutron Stars (INSs) have expanded from the more classical rotation-powered ones to other categories, like the Anomalous X-ray Pulsars (AXPs) and the Soft Gamma-ray Repeaters (SGRs), which make up the class of the magnetars, the radio-quiet INSs with X-ray thermal emission and, more recently, the enigmatic Compact Central Objects (CCOs) in supernov...
