Miniature astronomical spectrographs using arrayed-waveguide gratings: capabilities and limitations
The size of the optical elements (gratings, mirrors, lenses) in traditional astronomical spectrographs scales with telescope diameter (unless the instrument is operating at the diffraction limit). For large telescopes, this leads to spectrographs of enormous size and implied cost. The integrated photonic spectrograph offers the potential to break this scaling law and allow massively multiplexed...
متن کاملArrayed-waveguide-grating light collector for on-chip spectroscopy
We present a novel arrayed-waveguide-grating (AWG) device with improved external (biomedical) signal collection for use in on-chip spectroscopy. The collection efficiency of the device is compared to that of a standard AWG. We also present experimental results on the collection efficiency and size of the collection volume. Keywords-arrayed waveguide grating; spectroscopy; integrated optics
متن کاملArrayed Waveguide Grating for Polarized Raman Spectroscopy of Human Teeth
We designed an arrayed-waveguide grating spectrometer for the detection of early dental caries in teeth through polarized Raman spectroscopy. Measurement results on extracted human teeth demonstrate the feasibility of the approach. (Abstract) Keywords-component; Raman spectroscopy; integrated optics;
متن کاملArrayed Waveguide Grating Router
This paper discusses design, fabrication, and characterization of a 512 × 512 arrayed waveguide grating router (AWGR) with a channel spacing of 25 GHz. The dimensions of the AWGR is 16 mm × 11 mm and is fabricated on a 250 nm silicon-on-insulator platform. The measured channel crosstalk is approximately −4 dB without any compensation for the phase errors in the arrayed waveguides. The AWGR spec...
متن کاملMiniature Spectrographs: Characterization of Arrayed Waveguide Gratings for Astronomy
We present results from a laboratory characterization of integrated photonic arrayed-waveguide grating chips, which are a modified version of commercial arrayed-waveguide grating multiplexors, for the purposes of creating an integrated photonic spectrograph. Using a robust probing setup we measure the peak total efficiency of the chips to be ~75%. We measure the spectral resolution full-width h...
