Computer-generated holograms embedded in bulk silicon with nonlinear laser lithography
(IEEE, 2016)Recently, we have showed a direct laser writing method to form subsurface structures inside silicon by exploiting nonlinear interactions. Here, we demonstrate utilization of this phenomenon to create computer-generated ... -
Cumulant-based parametric multichannel FIR system identification methods
(Elsevier, 1994)In this paper, “least squares” and recursive methods for simultaneous identification of four nonminimum phase linear, time-invariant FIR systems are presented. The methods utilize the second- and fourth-order cumulants of ... -
Harmonic cantilevers for nanomechanical sensing of elastic properties
(IEEE, 2003-06)We present a micromachined scanning probe cantilever, in which a specific higher order flexural mode is designed to be resonant at an exact integer multiple of the fundamental resonance frequency. We have demonstrated that ... -
Hızlı seyrekleştirici dönüşüm öğrenme ile görüntü ters evrişimi
(IEEE, 2018-05)Görüntü ters evrişimi görüntülemede sık karşılaşılan ters problemlerden biridir. Doğal görüntüler bir dönüşüm uzayında seyrek olarak ifade edilebildikleri için seyreklik önsellerinin bu problemleri etkili bir şekilde ... -
Object detection using optical and LiDAR data fusion
(IEEE, 2016-07)Fusion of aerial optical and LiDAR data has been a popular problem in remote sensing as they carry complementary information for object detection. We describe a stratified method that involves separately thresholding the ... -
Optical waveguides written deep inside silicon by femtosecond laser
(OSA, 2017)Summary form only given. Photonic devices that can guide, transfer or modulate light are highly desired in electronics and integrated silicon photonics. Through the nonlinear processes taking place during ultrafast ...
