Integrated optical device for luminescence sensing

摘要

An integrated luminescence sensor includes a light pipe in optical communication with a luminescence sensing layer. A source of excitation illumination is coupled to the light pipe and disposed to direct excitation illumination toward the sensing layer. A luminescent light detector is also coupled to the light pipe and is disposed to detect luminescent illumination luminescing from the sensing layer, which luminescence is related to interaction between the sensing layer and a substance of interest.
