Abstract

This study demonstrates Bragg wavelength tuning, with maximum tunability of 114 GHz at 1561.8 nm using patterned ITO glass electrodes with 170 Vpp voltage at 1 kHz. The development of a cascaded architecture of such integrated liquid crystal devices operating at different Bragg wavelengths could pave the way towards true colorless add/drop modules for dynamic dense optical networks.
