Processing of Small Integrated Optical Spectrometer Devices with Femtosecond Laser Pulses — •Markus Thiel1, Günter Flachenecker2, Jörg Burgmeier1, and Wolfgang Schade1,2 — 1Institut für Energieforschung und Physikalische Technologien der TU Clausthal, EnergieCampus, Am Stollen 19 , 38640 Goslar — 2Fraunhofer Heinrich Hertz Institute, Fibre Optical Sensor Systems, EnergieCampus, Am Stollen 19, 38640 Goslar
Compact miniature spectrometers have, due to their advantage of size and cost-efficiency, increasing significants in networks based on fibre optics like telecommunication or dispersed optical sensor systems. Here we show first results of a spectrometer, which is processed directly into glass with femtosecond laser pulses. The design is a spatial heterodyne spectrometer, based on an array of Mach-Zehnder interferometers.[1] Fundamental parameters for processing waveguide structures are discussed and future applications for sensor networks are outlined. The design of the spectrometer is compared with conventional arrayed waveguide gratings.
