We report a type of high-speed microcell polarimeter that utilizes microelectrodes, liquid-crystal films, and ultrathin high-contrast polarizers, all integrated between the tips of two optical fibers. When combined with optimized nematic liquid-crystal materials, this compact (2.5>cm×0.5>cm ×0.5>cm) device offers excellent optical properties and continuous, high-speed operation at >2 kHz with moderately low operating voltages. It requires no bulk optical elements, and it shows excellent performance when implemented for the measurement of degree of polarization in 10-Gbit:s test systems. Polarimeters based on this design have promising potential applications in polarization analysis for high-speed optical communication systems.
