Proceedings of the Bipolar Circuits and Technology Meeting.
The authors discuss a 2:1 multiplexer operating from 100 Mb/s to 11.4 Gb/s, which was fabricated using a silicon nitride self-aligned process that features 0.6- mu m-wide arsenic-doped emitters with 4- mu m base-to-base pitch, deep trench isolation,

We have investigated the effect of spatial gain uniformity on the multiplication noise of InP/InGaAsP/InGaAs avalanche photodiodes (APD's) with separate absorption, "grading," and multiplication regions. APD's with localized regions of high gain exhi

We have successfully demonstrated a new type of logic circuit which provides an optical output pulse that is the AND function of two wavelength multiplexed optical input signals. The active components of this optically coupled logic gate are a trigge

Efficient small-signal modulation bandwidths of 30-40 MHz were achieved with three types of large area, small contact LED's suitable for use with optical fiber transmission lines. Much higher modulation rates are possible with about 6 dB/octave incre

High-speed operation of a long-wavelength (1.0µm ≲ λ ≲ 1.65µm) avalanche photodiode (APD) has been achieved with a heterojunction structure consisting of a wide-bandgap (InP) multiplication region and a narrow-bandgap (InGaAs) absorption regio

There is a little doubt that the spontaneous passage of gallstones occurs sometimes without pain or jaundice. This is probably more frequent than is realised. While the cholecystogram is a reliable investigation and of great assistance to the clinici

We report on the spatial uniformity of the gain M of InP/ InGaAsP/InGaAs avalanche photodiodes with separate absorption, grading, and multiplication regions (SAGM-APD's). Typically, these APD's exhibit less than 10 percent variation in the gain (for
