Detectors are composed of SiNx and TiN as absorbing layer, Al to form bimaterial legs, and integrated diffraction grating interferometer underneath each detector.https://biocil.github.io/tr/publication/2009_spiedef_ferhanoglu/Sun, 01 Jan 2017 00:00:00 +0000https://biocil.github.io/tr/publication/2009_spiedef_ferhanoglu/Parylene was used as the structural material due to its high thermal isolation and mismatch properties. Calculations reveal that the NETD performance of a thermo-mechanical array using Parylene can be significantly better than SiNx based designs and offer a theoretical NETD value <10mK assuming an optical readout with a high dynamic range detector array.https://biocil.github.io/tr/publication/2008_prime_toy/Sun, 01 Jan 2017 00:00:00 +0000https://biocil.github.io/tr/publication/2008_prime_toy/A novel thermo-mechanical infrared (IR) imaging array with integrated diffraction gratings for optical readout was fabricated and tested.https://biocil.github.io/tr/publication/2007_ptl_ferhanoglu/Sun, 01 Jan 2017 00:00:00 +0000https://biocil.github.io/tr/publication/2007_ptl_ferhanoglu/A two-wavelength readout method is developed that maintains high sensitivity while increasing the detection range, which is demonstrated using a MEMS spectrometer with integrated diffraction grating.https://biocil.github.io/tr/publication/2007_leos_ferhanoglu/Sun, 01 Jan 2017 00:00:00 +0000https://biocil.github.io/tr/publication/2007_leos_ferhanoglu/An uncooled thermal detector array with low NETD is designed and fabricated using MEMS bimaterial structures. A diffraction grating is embedded on the pixel membrane for sensing sub-nm mechanical deflections.https://biocil.github.io/tr/publication/2007_omn_toy/Sun, 01 Jan 2017 00:00:00 +0000https://biocil.github.io/tr/publication/2007_omn_toy/A two-wavelength readout method is developed that maintains high sensitivity while increasing the detection range from 105 nm to 1.7 um assuming sensitivity is maintained at >50% of the maximum sensitivity
