A 4x4 crossbar optical switch array consisting of 16 directional couplers is described. The device had an average insertion loss of 6dB. Fourteen of the couplers had crosstalk levels of
In(0.53)Ga(0.57)As p-i-n photodiodes have become the most suitable photodetectors for long wavelength (1-1.65 microns) optical fiber communication systems due to their low dark-currents of the orde
A reflectarray antenna is an attractive solution for reconfigurable antennas, for it has both advantages of arrays - beam shaping with fixed antenna - and reflectors - high efficiency single feed.
A CMOS output buffer which generates 100KECL logic levels is demonstrated. The final output stage consists of a single P-channel device.

In this letter, we propose two antenna grouping schemes for uplink Nx SC-FDMA MIMO systems, where the multiple component carriers can be divided into several groups which are handled by different a
White light emitting diode (WLED) technology has been regarded as an environment-friendly lighting in the future.
This TM presents a decision feedback equalizer (DFE) for a high-speed packet modem utilizing the normalized least mean squared (NLMS) tap update algorithm.
A low-power test pattern generation, named the low switching activity test pattern generation (LSA-TPG), is proposed to reduce the power dissipation of built-in self-test (BIST)-based circuits duri
We describe a high performance, fully ion implanted InP Junction FET developed for the monolithic integration of optoelectronic circuits.
