| Abstract | An integrated arrayed-waveguide grating fabricated in silicon-oxynitride technology is applied to Raman spectro-scopy. After its validation by reproducing the well-known spectrum of cyclohexane, polarized Raman spectra are measured of extracted human teeth containing localized initial carious lesions. Excellent agreement is obtained between the spectra of healthy and carious tooth enamel measured with our integrated device and spectra recorded using a conventional Raman spectrometer. Our results represent a step toward the realization of compact, handheld, integrated spectrometers, e.g. for the detection of dental caries at an early stage. © 2011 Optical Society of America. |
