PRESS RELEASE
FOR IMMEDIATE RELEASE
DEPOSITION SCIENCES PRODUCES 3200 GHZ OPTICAL BANDPASS FILTER USING PATENTED
REACTIVE SPUTTERING PROCESS.
CLEVELAND, OHIO, JUNE 1, 2000 - ADVANCED LIGHTING TECHNOLOGIES, INC. (NASDAQ:
ADLT), announced today that its Deposition Sciences Inc. (DSI) subsidiary has
produced the first 3200 GHz optical bandpass filter using its patented
MicroDyn(TM) reactive sputtering coating technology. This is an important
benchmark in DSI's DWDM filtER program to develop high yield mass-produced 200
GHz filters using MicroDyn(TM) metal oxide sputtering technology.
"Most of today's WDM and DWDM thin-film filters are produced using evaporation
or ion-assisted evaporation coating techniques," explains Eric Krisl, DSI's Vice
President of Corporate Engineering. "Evaporation technology already produces 200
GHz and 100 GHz optical band pass filters, but has inherent production
limitations. Device yields are low, and can be less than 5%. Successful
implementation of MicroDyn(TM) for these filters would provide higher yields and
the same or better bandwidth coverage as obtained using evaporation coating
techniques. This means MicroDyn(TM) may provide both lower cost and higher
performance DWDM devices for the telecom industry."
The 3200 GHz bandpass filters will be sold under the IsoFilter(TM) product line,
model number DS2400. DSI expects to begin the product qualification process for
these filters with potential customers this month. These 3200 GHz filters expand
the product line, which has featured such products as the IsoFilter(TM) power
tap (DS 2450), and the IsoFilter(TM) 980 and 1480 pump filters (DS 2430 and
2410).
DSI, a wholly owned subsidiary of Advanced Lighting Technologies, Inc., is an
advanced thin film coating company with a Telecommunications Business Unit in
Santa Rosa, California. Current products include WDM filters, highly reflective
films for DWDM applications, and optical fiber assemblies and micro-optics that
reduce insertion losses in DWDM, metro, and optical switching systems. DSI's
patented and proprietary coating equipment, advanced thin film processes, and
measurement capabilities are used in many of these products and systems.
