In this paper, a multi-path optical ring resonator (MpORR) structure on silicon on insulator (SOI) technology is proposed to sensitivity enhancement for chemical liquid sensing applications. It is designed on Silicon Dioxide (SiO2) substrate and Silicon material as the core of optical waveguides. The proposed multi-path optical ring resonator can be realized wide free spectral value (FSR) in order terra-hertz. Therefore, the sensitivity of the sensor can be enhanced. Analysis and optimization of the proposed multi-path optical ring resonator are discussed and reported for optical wavelength operation of 1550.The proposed device can be used for identifying difference liquid material precisely.
