Paper Abstract

We propose a wavelength-insensitive optical switch using twist nematic liquid crystal display (TN-LCD) panel for multi-mode or single-mode fiber communication systems application. Based on the simple and widely used TN-LCD structure, the optical switch has the potential advantages such as inexpensive, simple fabrication processes, and easy mass production. The preferable operating frequency of the device is 0.1 k to 10 k Hz ac wave. The critical and saturated voltage are as low as 3 Vrms and 5.8 Vrms, respectively. The high extinction ratio of 28.3 dB is obtained.
