Sensitivity Enhancement of Electric Field Sensor Using HC-1550 PCF Infiltaring by EBBA Liquid Crystal

Suha M. Khorsheed, Soror A. Mahdi, Hussain T. Saloom

Abstract: The implementation of the electric field sensor was carried out by using short length of hollow core (HC-1550) PCF. A diode laser was used with wavelength equal to 650nm has been used as a light source guide the light to the one side of the fiber, the other side infiltration with EBBA liquid crystal by capillary effect, where record the transmission spectra by using the fiber optic spectrometer. The proposed sensors are used in the next testing stage. For electric field sensing, the EBBA liquid crystal infiltrate the air holes for the hollow core (HC-1550) PCF. The infiltrated section of photonic crystal fiber was equal to ~1 cm. The results show that the power of transmission spectrum will be remains unchanged until reach the electric field intensity to 97.2 Vrms/mm. The region of the electric field sensor operating is between (97.2 Vrms/mm to 146.8 Vrms/mm). The sensitivity can be finding by the slope of transmission and electric field intensity. It has been obtained that reached 0.00123 dBm. mm/Vrms at 650 nm. These sensitivity amounts are acceptable in comparison with that mentioned in literatures, which indicate the correct path of the work flow and ensure the results validation
