We introduce a new GaAs/Al sub x Ga sub 1-sub x As single heterostructure, which allows local optical injection of a one-component confined plasma.

Bidirectional transmission at 90 Mbit/s over km of fiber using a single laser source is demonstrated.

Experimental results are presented which show that a narrow band reflection filter can be used for longitudinal mode selection in semiconductor lasers.

A one-mask metal-insulator-metal (MIM) capacitor using damascene Cu as the bottom electrode has been developed.

Bending induced losses in matched and depressed cladding single-mode fibers have been compared in a series of microbending and macrobending tests.

We present and analyze payload/label encoding based on a single Mach-Zehnder modulator, in which the payload is differential phase-shift keyed and the label is amplitude-shift keyed through modulat

We present an extensive theoretical investigation of the mechanical unzipping of double-stranded DNA under the influence of an applied force.

A 32 bit floating point signal processor is integrated with eight 16k x 4 bit SRAM chips on a 0.94" x 0.94" silicon substrate, enabling zero- wait- state access of the full 64k bytes of SRAM by the

We have done experiments on the detection of single photons at a wavelength of 1.3 micron using a gated Ge avalanche photodiode pulse biased above breakdown.
