We have developed two new etchant systems by adding H sub 2 O sub 2 and HBr into the conventional HCl-H sub 3 PO sub 4 etchant for the fabrication of InP-based channelled substrate heterostructure
A new class of fiber parametric amplifiers is demonstrated.
A theory of classical two and three body interatomic potentials is developed.
A brief summary of the emerging evidence for a new class of collective states of two-dimensional electrons in partially occupied excited Landau levels is presented.
We demonstrate an optical fiber mounting device which allows microlensed fibers to be pressed repeatedly against the cleaved facets of semiconductor laser diodes without causing significant impact
We propose remote amplification by reusing optical amplifiers in the ONU as in-line amplifiers in a power line independent switched power splitter and show that the budget can be substantially incr
The conventional base station will not long fulfill network needs.
Since World War II there have been major changes in exchange outside plant cable networks.
An (N, K) codebook C is a set of N unit-norm complex vectors in C-K. Optimal codebooks meeting the Welch bound with equality are desirable in a number of areas.
The new toll exchange, considerably larger than the existing one, deals not only with the regular toll traffic to and from the city of Amsterdam, but also with a considerable part of the internatio
