The reliability potentiality of quantum dash lasers was investigated. During 7000 hours under CW operation at 60°C junction temperature, no failure was observed.

High purity iron, cast and rolled more than 20 years ago, has largely maintained its bright surface finish over this period of time.

Long Term Evolution (LTE) is considered to be the natural evolution for current GSM-R system in high speed railway environments, not only for its technical advantages and increased performance, but

LTE-WLAN Aggregation (LWA) has recently emerged as a promising third generation partnership project (3GPP) Release 13 technology to efficiently aggregate long term evolution (LTE) and wireless loca

Fixed wireless access is becoming a major 5G application. We measured received power for 72 urban fixed wireless links at 5.8 GHz over a period of 48 hours each.

We demonstrate the world's first long term optical PMD compensation for an OC-192 (9.95328 Gb/s SONET) signal on the installed fiber infrastructure of a network operator in East Texas.

We show that long wave short wave resonance can be achieved in a second-order nonlinear negative refractive index medium when the short wave lies on the negative index branch.

We report the first long wavelength photoconductive detectors fabricated from GaSb epitaxially grown on a Si substrate. Responsivities of 0.18 A/W are obtained at a wavelength of 1.5microns.

System aspects of ultra low loss fluoride fibers, such as optical nonlinearities, dispersion characteristics, and source and detector capabilities, were analyzed to determine the ultimate performan

An empirical model has been developed that relates the long wavelength LED bandwidth of 62.5/125 micrometer cables to 1. 3 micrometer laser bandwidth and LED spectral characteristics.
