Surveillance is seen as a key tool to detect terrorist activities or to counteract attacks on critical communication infrastructure. Everybody is in those systems to some degree under suspicion.
In a cable-modem network, a cable modem (CM) talks to a cable- modem termination system (CMTS) over a traditional cable-television network.
A novel technique for monitoring the alignment status between the pulse carver and data modulator for return-to-zero (RZ) differential phase-shift keying (DPSK) systems is proposed and demonstrated
A novel technique for monitoring the alignment status between the pulse carver and data modulator for return-to-zero (RZ) differential phase-shift keying (DPSK) systems is proposed and demonstrated
The design of a coupling between a semiconductor laser and a single-mode fiber, or between any two optical or acoustical elements that support Gaussian modes, is presented as a trade off among coup
Alignment method for materials with cholesteric to smectic C phase transitions is described.
We have developed a method for producing alignment marks on a wafer using exposed photoresist.
SCBR lasers consist of 1.55micron channeled-substrate buried heterostructure lasers attached to silicon chip Bragg reflectors which stabilize single longitudinal mode operation.
High-frequency high-electron-mobility transistors (HEMTs) were fabricated on AlInN/AlN/GaN heterostructures grown by low-pressure metal-organic chemical vapor deposition on a SiC substrate.
Complexes of alkali metal salts with various polymers have for some time recognized as fast ionic conductors.
