Abstract. Polymeric electro-optic materials have recently been developed that, when fabri-
cated into devices such as Mach-Zehnder interferometers, permit drive (Vπ) voltages of less
than 1 V to be realized at the munications wavelength of and microns. Op-
eration of polymeric electro-optic modulators to frequencies (bandwidths) of greater than
100 GHz has been demonstrated. The total insertion loss of polymeric electro-optic modu-
lators has been reduced to values as low as 5 dB, which petitive with values obtained
for lithium niobate modulators and is much lower than that obtained for gallium arsenide
electro-absorptive modulators. Polymeric electro-optic modulators can be operated for
long periods of time at temperatures on the order of 100 °C. Techniques have been devel-
oped for seamlessly integrating polymeric electro-optic circuitry with passive low loss op-
tical circuitry (., silica long-haul transmission fiber and medium-range fluoropolymer
fibers) and with very large scale integration (VLSI) semiconductor electronics. These ad-
vances have created a considerable interest in mercialization of polymeric electro-
optic materials. Polymeric electro-optic materials are now being evaluated for applications
such as phased array radar, satellite and fiber munications, cable television (CATV),
optical gyroscopes, electronic counter measure (ECM) systems, backplane interconnects
for high-puters, ultrafast (100 Gbit/s) analog-to-digital (A/D) converters, land
mine detection, radio frequency (rf) photonics, and spatial light modulators. This review
discusses the structure-function relationsh
