All-passive pixel super-resolution of time-stretch imaging
Antony C. S. Chan, Ho-Cheung Ng, Sharat C. V. Bogaraju +3
Based on image encoding in a serial-temporal format, optical time-stretch imaging entails a stringent requirement of state-of-the- art fast data acquisition unit in order to preser…
Asymmetric-detection time-stretch optical microscopy (ATOM) for ultrafast high-contrast cellular imaging in flow
Terence T. W. Wong, Andy K. S. Lau, Kenneth K. Y. Ho +10
Accelerating imaging speed in optical microscopy is often realized at the expense of image contrast, image resolution, and detection sensitivity- a common predicament for advancing…
Shot-to-shot spectrally-resolved characterization of continuous-wave-triggered supercontinuum near 1 um
Zhibo Ren, Yi Qiu, Kenneth K. Y. Wong +1
We demonstrate shot-to-shot (at a rate of 20 MHz), broadband (>200 nm), spectrally-resolved (spectral resolution of 0.2 nm) statistical characterization of continuous-wave-triggere…
Periodically-Poled Silicon [Updated]
Nick K. Hon, Kevin K. Tsia, Daniel R. Solli +1
We propose a new class of photonic devices based on periodic stress fields in silicon that enable second-order nonlinearity as well as quasi-phase matching. Periodically-poled sili…
Amplified Dispersive Fourier-Transform Imaging for Ultrafast Displacement Sensing and Barcode Reading
Keisuke Goda, Kevin K. Tsia, Bahram Jalali
Dispersive Fourier transformation is a powerful technique in which the spectrum of an optical pulse is mapped into a time-domain waveform using chromatic dispersion. It replaces a…
Energy Scavenging in Silicon Raman Amplifiers
S. Fathpour, K. K. Tsia, B. Jalali
Continuous-wave Raman amplification in silicon waveguides with negative electrical power dissipation is reported. It is shown that a p-n junction can simultaneously achieve carrier…
