In this paper, a multi-path optical ring resonator (MpORR) on silicon-on-insolator (SOI) is proposed for sensitivity enhancement in liquid chemical 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 with a wide free spectral value (FSR) of 3 THz. Therefore, the...
High sensitivity environmental sensors with a simple and compact structure are required to monitor unwanted pollution such as liquid waste. In this paper an environmental sensor liquid waste using a polymer multi-coupled ring resonator (MCRR) structure is proposed. The proposed structure consists of polymeric materials on silicon substrate. Also discussed the influence of different refractive index...
