Abstract: An optical sensor, sensing system and method of sensing employ a half-core hollow optical waveguide adjacent to a surface of an optical waveguide layer of a substrate. The half-core hollow optical waveguide and the adjacent optical waveguide layer cooperatively provide both an optical path that confines and guides an optical signal and an internal hollow channel. The optical path and channel extend longitudinally along a hollow core of the half-core hollow optical waveguide. The system further includes an optical source at an input of the optical path and an optical detector at an output of the optical path. A spectroscopic interaction between an analyte material that is introduced into the channel and an optical signal propagating along the optical path determines a characteristic of the analyte material.

Abstract: A Raman spectroscopy system is disclosed which includes a sub-wavelength resonant grating filter and a photodiode with integrated sub-wavelength resonant grating filter are disclosed. The resonant grating filter comprises an array of diffraction elements having a periodic spacing that is less than the wavelength of radiation to be filtered and which are formed over a waveguide layer. The filter, which can reject a specific wavelength of radiation, can be placed between a Raman sample and a Raman detector in order to filter radiation that is elastically scattered from the sample while transmitting other wavelengths. The wavelength rejected by the filter can be selected by tilting the filter with respect to the radiation incident upon the filter.
