In this paper we present and discuss options for increasing the serial bitrate of TDM-PON beyond 10 Gbps.
Hydrostatic pressure (up to 16 kbar) has been used to investigate the transport properties of GaInAs-AlInAs heterojunctions in the range 0-18 tesla and 4.2 - 300K.
The fabrication of optical fibers with the MCVD process is improved by incorporating small amounts of phosphorus into the silica lattice.
The Aluminum flow under various excimer laser fluences and substrate temperatures has been studied systematically.
Rapid photothermal annealing is based on the use of vacuum ultraviolet (VUV) photons as the source of optical energy and tungsten halogen lamps as the source of optical and thermal energy.
Resist outgassing during exposure is a problem which is of importance both in UV lithography (248 nm or 193 nm) and vacuum lithographies (e.g., e-beam).
