Abstract

Almost all current microring resonator (MRR) based sensors rely on a wavelength shift detection scheme. This involves (i) expensive tunable lasers as an input source and (ii) optical spectrum analyzers as a detector, which leads to overall bulky configuration, high cost, and complex arrangement. Here, we propose a low-cost, tapered waveguide MRR-based gas sensor that uses a simple intensity-level detection method. It employs (1) a low-cost laser source and (2) a photodetector. The MRR is coated with graphene to detect the specific target element. This design can significantly reduce the overall cost and complexity of the sensing system.
