Abstract:We have designed a polarization insensitive arrayed-waveguide grating as a wavelength-selective device for Raman spectroscopy of the skin. The integrated spectrometer was characterized. Experimental results are presented and compared with a simulation. We tested our device in a novel confocal arrangement with a similar device that was used for focusing the excitation signal onto the sample. Experimental results on the collection efficiency and volume are presented together with a demonstration of multi-wavelength imaging.
