Abstract

A photonic crystal based collection probe is provided. The probe includes a photonic crystal configured to guide and condition a beam of Raman scattered photons. Further, the device includes a spectrograph in optical communication with the photonic crystal and configured to receive Raman scattering from the photonic crystal. The device may be employed in a Raman spectrometer system.
