Research Frontiers Material and process parameters have been
refined to control birefringence and maintain replication
integrity. New long flow grades of the materials have been
developed specifically for the CD market. Polymeric Materials
for Photonics Photonics is a technology analogous to electronics
in which the photon replaces the electron as the working
particle. Many of the applications now accomplished
electronically, including transmission, switching,
amplification, and modulation, can also be realized using
photonics, and there are advantages to be gained by converting
to a photon-based technology in some areas. Transmission of
light in fiber-optic systems is the direct analogy of electrical
transmission in coaxial cable systems. Fiber-optic systems are
