Abstract:
The development of ultra-compact and sensitive sensing structures with minimal sample requirement for accurate sensing have been of great recent interest for multiple applications including bio and environmental sensing, chemical agent detection, and bio- threat detection. With recent advancement in the development of design and fabrication tools for photonic nanostructures, integrated photonic platforms are a strong candidate for the development of such sensing structures.
In this talk, the use of high-Q integrated photonic resonators for forming ultra-compact highly sensitive chip-scale multiplexed sensors and spectrometers for realization of photonic lab-on-a-chip sensing structures will be presented. Major challenges in realization of such devices including fabrication imperfections and errors due to environmental effects as well as reliable solutions will be discussed.
