The reliability performance of 128/spl times/ 128 optical cross-connects (OXCs) based on microelectrooptomechanical systems (MEOMS) switch matrices is considered. First, we compare a strictly nonblocking wavelength selective switch with a strictly no

The use of tunable lasers in a long haul network has two applications: sparing and optical networking. The justification for sparing is that the use of tunable lasers reduces the number of extra transponders (one for every wavelength) that service pr

An InGaAsP/InP laser monolithically integrated with a rear facet monitor and a fiber V-groove has been demonstrated for the first time. The integrated device incorporates an etched-facet laser fabricated using an in situ, multistep, reactive ion etch

It was found that oxygen chemisorption on ZnO surfaces is accelerated by as much as three orders of magnitude after illumination in the presence of CO + O 2 . This accelerated chemisorption is characterized by electron transfer and thermal activation

A constant voltage scaling scheme is examined for the enhancement of frequency and power performance of FETs. For low electric fields, this scheme is self-consistent within Shockley's formulation and improves the overall frequency and power performan

Electron beam stimulated micro- and macroscopic phenomena are reported for CdS surfaces irradiated with a two keV electron beam. Microscopic effects - confined strictly to the irradiated area - were observed in the presence of water vapor of a partia

A gate probe method has been developed to accurately determine source, drain, and channel resistances of MESFET's. The method employs the gate current crowding phenomenon at higher drain currents. An exact equation was derived for the resistances who

A method based on monitoring the thermally stimulated drain conductance (TSDC) under trap filling and emptying bias-temperature sequences is developed for directly characterizing high defect density AlGaAs layers in high electron mobility transistors
