  • Uncooled infrared thermo-mechanical Detector Array: Design, fabrication and testing
    Sensors and Actuators A: Physical, 2009
    Co-Authors: M. Fatih Toy, Hamdi Torun, Onur Ferhanoglu, Hakan Urey
    Abstract:

    Thermo-mechanical Detector Arrays in the 160 × 120 Array format are designed, fabricated, and tested. Detectors are composed of SiNx and TiN as absorbing layer, Al to form bimaterial legs, and integrated diffraction grating interferometer underneath each Detector. The Detector Array is a passive component and the optical readout is performed remotely with a laser and CCD camera. All noise sources are considered in making a detailed noise equivalent temperature difference (NETD) estimation, which revealed 12-bit CCD camera for the readout.

  • Thermo-Mechanical Detector Array with Optical Readout
    IEEE LEOS International Conference on Optical MEMS and Their Applications Conference 2006., 2006
    Co-Authors: Hamdi Torun, Onur Ferhanoglu, Hakan Urey
    Abstract:

    An uncooled thermal Detector Array with low NETD is designed and fabricated using MEMS bimaterial structures that bend in response to thermal change. A diffraction grating placed underneath each pixel allows sensing sub-nm mechanical deflections

  • High-speed femtosecond pump-probe spectroscopy with a smart pixel Detector Array
    Optics Letters, 2003
    Co-Authors: Stephane Bourquin, Rohit P. Prasankumar, Theo Lasser, James G Fujimoto, Franz X. Kärtner, Rene-paul Salathe
    Abstract:

    A new femtosecond pump–probe spectroscopy technique is demonstrated that permits the high-speed, parallel acquisition of pump–probe measurements at multiple wavelengths. This is made possible by use of a novel, two-dimensional smart pixel Detector Array that performs amplitude demodulation in real time on each pixel. This Detector Array can not only achieve sensitivities comparable with lock-in amplification but also simultaneously performs demodulation of probe transmission signals at multiple wavelengths, thus permitting rapid time- and wavelength-resolved femtosecond pump–probe spectroscopy. Measurements on a thin sample of bulk GaAs are performed across 58 simultaneous wavelengths. Differential probe transmission changes as small as ~2×10-4 can be measured over a 5-ps delay scan in only ~3 min . This technology can be applied to a wide range of pump–probe measurements in condensed matter, chemistry, and biology.

  • Femtosecond pump-probe spectroscopy using a two-dimensional smart pixel Detector Array
    The Thirteenth International Conference on Ultrafast Phenomena, 2002
    Co-Authors: Stephane Bourquin, Franz X. Kaertner, Rohit P. Prasankumar, Theo Lasser, James G Fujimoto, Uwe Morgner, Rene-paul Salathe
    Abstract:

    A new method for simultaneously acquiring pump-probe signals at several wavelengths using a smart pixel Detector Array and broadband femtosecond laser has been demonstrated and promises to be a powerful technology for performing rapid, high sensitivity, wavelength-dependent pump-probe spectroscopy
