We experimentally investigate PM-32QAM with up to 16 subcarriers per wavelength and demonstrate that at a net bitrate of 350 Gbit/s, the distance can be increased by 300 km in WDM transmission usin

The fabrication and performance characteristics of frequency tunable two-section distributed feedback lasers are reported.

Loops are the facilities between the local central office and the subscriber. For the most part, the individual customer's loop is a pair of metallic conductors.

The experiments by the author and L. H. Germer, by G. P. Thomson and by others from which the wave properties of electrons are adduced are briefly described.

The production of integrated circuits involves some of the most sophisticated and precise manufacturing techniques ever developed.

The linear and quadratic electrooptic coefficients in narrow single and strongly coupled GaAs-AlxGa1-xAs quantum wells have been measured, The quadratic electrooptic effect is enhanced over that of

Tin alloys such as Sn-0.7% Cu and Sn-2% Bi were identified as viable alternatives to tin-lead finishes.

An analytical solution for the metal resistance-controlled plating current distribution on circular wafers is obtained to determine the conditions under which a uniform metal film can be electro-de

Electro-reflectance spectroscopy of Ge(x)Si(1-x) decoupled multiple quantum-well structures grown by MBE has been used to yield confinement energy and strain shifts for the E(0)) and E(1) optical
