Abstract

In this paper we analyze the possibilities of developing efficient and low-cost multichannel photonic sensor system using SiO₂:TiO₂ photonic integrated circuit (PIC) technology. We examine numerically the possibility of using optical ring resonator as a fundamental building block of the system. The most convenient ring resonator configuration is shown providing both relatively high sensitivity (125 nm/RIU) and relatively wide free spectral range (9.6 nm) large enough for serial connection of multiple rings. Our study is completed by the report of recent advances in fabrication technology obtained in our project.
