Abstract
|
| The
explosive demand for bandwidth for data networking applications continues
to drive photonics technologies toward ever-increasing capacity in
the backbone fiber network and toward flexible optical networking.
Already Tb/s (per fiber) transmission systems have been announced,
and it can be expected that in the next several years we will begin
to be limited by the 50 THz transmission window of silica optical
fiber. |
| This
evolution places stringent demands on the materials and devices incorporated
in network elements. Extensive research is underway on optical cross-connects,
optical packet switching, high port count mux-demux devices, reconfigurable
add-drop multiplexers, wavelength agile lasers, broadband fiber amplifiers,
high capacity fiber designs, and elements for network management.
These devices are based on a number of materials platforms including
compound semiconductor technology, silica-on-silicon, lithium niobate,
MEMS technology, polymer and silica optical fiber, and ceramic and
plastic packaging technologies. |
|
The evolution
of these materials technologies for devices in this new century
will be discussed in terms of device and systems needs. |

| Alastair
M. Glass is currently Director of the Photonic Components Research
Laboratory of Bell Laboratories, Lucent Technologies. In this capacity
he is responsible for optical fiber, optical waveguide, and semiconductor
lasers and detector research and development for communication applications.
Since joining Bell Labs in 1967, Dr. Glass has been involved in a
number of different fields of materials research relating to optical
and electronic devices. This includes ferroelectric and piezoelectric
materials, compound semiconductors, and dielectric insulators. In
his personal research he is probably best known for his pioneering
work on novel optical phenomena in electro-optic materials including
pyroelectric infrared detectors and photorefractive effects for image
processing. He has been an active member of the Optical Society for
several years and is currently an OSA Fellow. He has served on a number
of organizing committees including general co-chair of CLEO 1993.
Dr. Glass has served on many government advisory panels. He is currently
a member of the NRC Committee on Optical Science and Engineering (COSE)
and previously chaired the National Materials Advisory Board studies
of process challenges in compound semiconductors. He authored two
books, some 150 publications, and 25 patents. He is a Fellow of the
IEEE, the Optical Society of America, and has been a member of the
National Academy of Engineering since 1987. |
