In the recent past short-wave high-power valves have frequently failed through local melting of the glass. Investigation has shown the cause to be dielectric losses.

We present designs for a low-loss mode coupler based on multiple Gaussian spots that can selectively address spatial and polarization modes of a few-mode fiber.

We present the theory for a novel low-loss mode coupler based on multiple Gaussian spots, that can selectively address all spatial and polarization modes of a few-mode fiber.

Fabry-Perot and distributed feedback spot size converted 1.3 /spl mu/m lasers are demonstrated with competitive performance (/spl sim/10 mA threshold, >0.30 W/A slope) and narrow (16/spl times/9

Describes a motor-driven auger provided with manually controlled feed. The auger is mounted on a universal coupling, and is adjustable in any direction to 45deg.

We numerically compare the performance of set partitioned (SP) dual polarization 16QAM formats with that of PDM-QPSK and PDM-8QAM with channel coding.

In layer 2/3 pyramidal neurons of barrel cortex in vivo, calcium ion concentration ({[}Ca2+]) transients in apical dendrites evoked by sodium action potentials are limited to regions close to the s

One of the consequences of selective fading with waves below 100 m.

In this work we have considered direct-sequence transmission for indoor wireless communications.

In this paper, we analyze the recently proposed downlink space-time-frequency spreading code-division multiple-access (STFS-CDMA) scheme.
