Dr. Richardson joined the Clemson
team in January 2005, following her previous post
as Associate Professor of Optics, Chemistry and
Mechanical, Materials and Aerospace Engineering
at the University of Central Florida’s, CREOL,
College of Optics and Photonics, where she was
for 12 years. Following a leave of absence at SCHOTT
North America’s Regional R&D in Duryea PA, where she served as manager
of their Materials Development and Technologies
groups between January 2002 and August 2003, Dr.
Richardson returned to UCF to resume her research
and academic training activities which include
numerous domestic and international programs associated
with undergraduate and graduate students.
Dr. Richardson joined UCF in 1992 following several
years at the University of Rochester’s Laboratory
for Laser Energetics where she conducted research
on ion-exchange strengthened laser glass, passive
and active liquid crystal-based optics and sol
gel-derived materials. All of her academic degrees
are from the New York State College of Ceramics
at Alfred University [B.S. Ceramic Engineering,
’82, M.S. Glass Science, ’88 and PhD Ceramics with
thesis work in glass science and engineering, ‘92].
Dr. Richardson currently runs the Glass Processing
and Characterization Laboratory (GPCL) within the Center
for Optical Materials Science Engineering and Technology (COMSET)
at Clemson where her team carries out synthesis
and characterization of novel glass and glass ceramic
materials for optical applications. Her research
programs examine the role of structure/property
relationships in a range of glass and ceramic media
and in addition to supervising research programs
in infrared glasses for use in integrated optics
applications, her group also has industrial and
government supported research programs evaluating
materials for molded optics, the use of non-oxide
glasses in chem-bio planar sensors, and in nano-composites
for advanced detection applications. She has authored
more than 95 refereed publications, proceedings
and book chapters, and has organized and chaired
numerous domestic and international meetings within
her discipline.
Professor Richardson is a past-Chair of the Glass
and Optical Materials Division (GOMD) of the American
Ceramic Society and the President-elect of the National
Institute of Ceramic Engineers (NICE). She currently
serves on advisory boards of numerous organizations,
including Virginia Tech’s Materials Science and Engineering
Department, the NSF-ERC on Mid-Infrared Technologies
for Health and the Environment (MIRTHE) at
Princeton University and as part of the Australian
Research Council’s Centre of Excellence for Ultrahigh-bandwidth
Devices for Optical Systems (CUDOS), in Sydney
Australia. She is a recognized world leader in infrared
glass research, is a Fellow of the American Ceramic
Society, the Society of Glass Technology (UK), and
most recently, the International Society of Optics
and Photonics (SPIE). Since 2006, she has served
as a member of the Board of Trustees at Alfred University.
Abstract - Design,
Fabrication and Integration of High Index Contrast
(HIC) Chalcogenide Glass Waveguides on a Silicon
Platform
Chalcogenide glasses have been widely explored
for more than two decades for use in bulk,
planar and fiber-based optical components.
Successful incorporation of these materials
into commercially-relevant systems requires
specific tailoring of chemistry, structure
and properties of the glass to meet the stringent
optical and environmental stability needs of
the systems they reside in. Additionally,
the possibility for commercially viable integration
towards on-chip devices suitable for a range
of applications that span measurement, sensing
and optical switching, will rely on the ability
to fabricate such structures with high fidelity
using proven fabrication platforms suitable
for scalable manufacturing. We demonstrate
results of a Si-CMOS-compatible lift-off fabrication
route to monolithically integrate chalcogenide
glass waveguides on a silicon platform. The
resulting waveguides will be utilized in an
on-chip chemical sensor possessing high sensitivity
and specificity to a target liquid analyte.
As a novel route of glass film patterning,
lift-off processing and the subsequent devices
it enables will allow the transition of such
components from laboratory prototypes to commercial
manufacturing platforms.
