Portable Automatic Micro-Ring Resonator System Using a Subwavelength Grating Metamaterial Waveguide for High-Sensitivity Real-Time Optical-Biosensing Applications
As the needs for bio-related detections continue to intensify in the healthcare industry due to the COVID-19 pandemic, our work on Si-microring slow-light systems comes as a timely aide with its small size, fast screening, and early diagnosis capabilities. The presented portable system integrates Si photonics with automated mechanical configurations in a platform that provides faster and real-time readouts, higher sensitivities, all working within the optical telecommunication bands, and ready for portable remote area point-of-care applications. With different receptors immobilized on the chip surface, it is also good for open applications in heavy metal detection, virus examination, and cancer diagnosis... Read more
