Paper Abstract

We propose electrically tunable periodically segmented waveguides (PSW) using liquid crystals in their structure. Duty cycles are varied showing that light diffracts and refocuses periodically through the liquid crystal core PSW, when an external voltage is applied on it. The propagation characteristics are analyzed for different values of effective refractive index, duty cycle and external voltage applied. The liquid crystal core PSW performance analyzed presents a device that can works as a polarizer and mode size converter for transversal mode polarization, an important and desired requisite in photonics circuits devices.
