The main impairment of differential-phase-shift-keyed communication systems is phase jitter.

Many large scale computing applications are not only compute- intensive, but memory intensive as well.

Here we report on the use of regrowth over a patterned subcollector to achieve a reduction in the base-collector capacitance, C sub BC , for InP/InGaAs latticed matched to InP based HBT devices.

For the standard triple mesa process typically used in the fabrication of III-V heterostructure bipolar transistors (HBT's) the base-collector capacitance becomes a limiting parasitic as the emitte

A fiber Lyot depolarizer was used to reduce the degree of polarization (DOP) of a laser pump diode.

We have demonstrated an InGaAs/InP pseudo-heterojunction bipolar transistor (PHBT) with InP passivation.

GaInAsSb/AlGaAsSb injection lasers have been fabricated with increased Al concentration in the cladding layers.

This paper presents a new and simple technique to reduce error propagation in DPCM image coders that employ adaptive switchingtype prediction.

We present reduction theorems for the problem of optimal unambiguous state discrimination of two general density matrices.
