Integrated AWG Spectrometer for On-chip Optical Coherence Tomography and Raman Spectroscopy

Silicon oxynitride-based arrayed waveguide grating (AWG) spectrometers were designed for on-chip spect ral-domain optical coherence tomography (OCT) systems and Rama n spectroscopy of the skin. A novel geometrical layou t for Raman spectroscopy was introduced to reduce loss. Measure m nts show that integrated optics has a good potential for min iaturizing… CONTINUE READING
