ADVISORY...for Wednesday (Aug. 1)

--(BUSINESS WIRE)

Invited Paper Presented at IEEE/LEOS Summer Topical Meetings in

Copper Mountain, Colo.

WHAT: Dr. J.C. Chiao from Chorum Technologies in Richardson, Texas, will
present his invited paper on liquid-crystal optical harmonic equalizers at 2001
IEEE/LEOS Summer Topical Meetings in Copper Mountain, Colo. The Summer Topical
Meeting Series is sponsored, organized and managed by the IEEE Lasers and
Electro-Optics Society to facilitate information exchange between technical
communities using or affected by rapidly growing areas of technology. Summer
Topicals 2001 consists of four meetings (Advanced Semiconductor Lasers and
Application; Ultraviolet and Blue Lasers and their Applications; Ultralong Haul
DWDM Transmission and Networking; and WDM Components) running simultaneously
over the course of 3 days, July 30 to August 1: In his paper for WDM
Components, Dr. Chiao will discuss the functionality and performance of an
optical harmonic equalizer for dynamic gain equalization and manipulation using
all-optical liquid-crystal modulators and the harmonic synthesis approach. WHO:
