Welcome to Photonics Laboratory @ UCLA
|
|
The Photonics Laboratory at UCLA performs multi-disciplinary research and
development in the fields of silicon photonics, microwave photonics, and biophotonics for biomedical
and defense applications. The Lab has two complementary missions. The first is to solve critical
problems faced by defense, commercial industries, and medicine through innovative approaches that
enable revolutionary advances in devices or systems. The second and equally important mission is to
produce creative and highly skilled scientists and engineers who will be the driving force for
technological innovation in the 21st century.

Nature photonics (January
2013): Dispersive Fourier transformation is an emerging measurement technique that overcomes the
speed limitations of traditional optical instruments and enables fast continuous single-shot
measurements in optical sensing, spectroscopy and imaging. Using chromatic dispersion, dispersive
Fourier transformation maps the spectrum of an optical pulse to a temporal waveform whose intensity
mimics the spectrum, thus allowing a single-pixel photodetector to capture the spectrum at a scan
rate significantly beyond what is possible with conventional space-domain spectrometers. Over the
past decade, this method has brought us a new class of real-time instruments the permit the capture
of rare events such as optical rogue waves and rare cancer cells in blood, which would otherwise be
missed using conventional instruments. |
Nature photonics (January
2013): Stochastically driven nonlinear processes are responsible for spontaneous pattern formation
and instabilities in numerous natural and artificial systems, including well-known examples such as
sand ripples, cloud formations, water waves, animal pigmentation and heart rhythms. Technologically,
a type of such self-amplification drives free-electron lasers and optical supercontinuum sources
whose radiation qualities, however, suffer from the stochastic origins. Through time-resolved
observations, we identify intrinsic properties of these fluctuations that are hidden in ensemble
measurements. We acquire single-shot spectra of modulation instability produced by laser pulses in
glass fibre at megahertz real-time capture rates. The temporally confined nature of the gain
physically limits the number of amplified modes, which form an antibunched arrangement as identified
from a statistical analysis of the data. These dynamics provide an example of pattern competition and
interaction in confined nonlinear systems. |
 Our work about
the high-throughput single-microparticle imaging flow analyzer has been published in
PNAS online and
covered in
UCLA Newsroom and
PNAS's
Highlights. The technology can take a picture of every single cell in a microfluidic channel with
a record high throughput of 100,000 cells/s and perform non-stop image-based cell classification in
real time. It holds promise for a broad range of applications such as high-throughput screening,
cancer detection, and stem cell research. The work has been highlighted in
TIME Magazine and
OPN. |
