Detection of 532nm Laser Light using a TiO2 Nanotube Integrated Microwave Resonator

Popis výsledku v původním jazyce

Optical sensors play an important role in applications of the biomedical industry and in monitoring potentially hazardous gases. This paper presents an integration of TiO2 nanotube (TNT) membranes coated on a microwave split ring resonator (SRR) to detect a 532 nm laser light. A SRR was designed with integrated TNT membranes at an operational frequency of 8.006 GHz with a resonant notch amplitude of -11.4 dB. The illumination of TiO2 changed the dielectric properties (optical properties of the TiO2) of the material, and this variation was monitored through the transmission coefficient S21. The designed integrated microwave resonator achieved a resonant amplitude change of 0.6 dB with a 6 MHz frequency downshift in a duration of 10 seconds of 532 nm laser exposure. The laser operated at a power of 5 mW and was located at a distance of 30 cm above the target resonator. The proposed design is the first exploration of the integration of TNT membranes with a microwave resonator for pioneering new forms of optical sensors.
