Ky. Lee et al., WAVELENGTH-INSENSITIVE OPTICAL SWITCH - ANOTHER APPLICATION OF THE TWIST NEMATIC LIQUID-CRYSTAL DISPLAY PANEL, Microwave and optical technology letters, 13(6), 1996, pp. 351-354
We propose a wavelength-insensitive optical switch that has a twist ne
matic liquid crystal display (TN-LCD) panel for multimode or single-mo
de fiber communication systems application. The preferable operating f
requency of the device is 0.1k-10k Hz ac wave. The critical and satura
ted voltages are as low as 3 Vrms and 5.8 Vrms, respectively. A high e
xtinction ratio of 28.3 dB is obtained. (C) 1996 John Wiley & Sons, In
