We have characterized the performance of a single-ended intradyne receiver when multiple wavelength-division multiplexed (WDM) channels are incident. Detection of a single 40 Gb/s dual-polarization QPSK channel is achieved within a band of up to 17 W

Following extension of fisheries jurisdiction to 200 nautical miles by Coastal States in the Northwest Atlantic in 1977, the Northwest Atlantic Fisheries Organization (NAFO) was established through a multilateral convention. NAFO differed substantial

The identification of substitutional shallow donors in GaAs by optical techniques has been problematic because of the extremely small chemical shifts of these effective-masslike impurities. Photoluminescence has been successfully applied in identifyi

Digital electronic equalization is a key enabler for the cost-effective deployment of 10 Gb/s optical transmission in metro and regional core networks. The wider dispersion tolerance enabled by digital equalization eliminates the need for Dispersion
