Submillisecond response variable optical attenuator based on sheared polymer network liquid crystal.

چکیده
We demonstrate a variable optical attenuator (VOA) at lambda=1.55 microm using a sheared polymer network liquid crystal (SPNLC). The SPNLC exhibits a fast response time and weak wavelength dependency. Comparing with other polymer-stabilized liquid crystals, the SPNLC has lower driving voltage and negligible light scattering loss when the wavelength exceeds 700 nm. A reflection type VOA with ~0.24 ms response time and -32 dB dynamic range is demonstrated at room temperature and 35 Vrms voltage.

Variable optical attenuator based on polymer stabilized twisted nematic liquid crystal.
A variable optical attenuator (VOA) based on polymer stabilized twisted nematic (PSTN) liquid crystal (LC) is demonstrated. Comparing with the normal twisted nematic LC-based VOA, PSTN exhibits a much faster response time. Moreover, the polymer networks effectively eliminate the backflow effect which exists in the normal TNLC cell. The attenuation mechanism of the PSTN LC was studied. Both pola...
متن کاملVariable optical attenuator with a polymer-stabilized dual-frequency liquid crystal.
A transmission-type variable optical attenuator (VOA) based on a polymer-stabilized dual-frequency liquid crystal (PSDFLC) is demonstrated at gamma = 1.55 microm. The VOA is highly transparent in the voltage-off state but scatters light in the voltage-on state. By using a birefringent beam displacer incorporated with half-wave plates, we can obtain a VOA that is polarization independent and tha...

A reflective-type polymer-stabilized cholesteric liquid crystal (PSCLC) cell was demonstrated at 1⁄4 1550 nm laser wavelength. It showed a high attenuation range ( 30 dB), a low operating voltage ( 12Vrms), a highly efficient polarizationindependent behavior and flat wavelength dependence in the range of 1525–1575 nm. The combined effects of curing temperature, chiral dopant, and monomer concen...
متن کاملHysteresis-free and submillisecond-response polymer network liquid crystal.
We demonstrate a polymer network liquid crystal (PNLC) with negligible hysteresis while keeping submillisecond response time. By doping about 1% dodecyl acrylate (C12A) into the liquid crystal/monomer precursor, both hysteresis and residual birefringence are almost completely eliminated. The operating voltage and scattering properties remain nearly intact, but the tradeoff is enhanced double re...
متن کاملFast-Response Liquid Crystal Microlens
Electrically tunable liquid crystal microlenses have attracted strong research attention due to their advantages of tunable focusing, voltage actuation, low power consumption, simple fabrication, compact structure, and good stability. They are expected to be essential optical devices with widespread applications. However, the slow response time of nematic liquid crystal (LC) microlenses has bee...
