January 2020: Our recent work on Photonic Integrated Field-Programmable
Disk Array Signal Processor has been published in Nature Communications. In the article,
a scalable photonic integrated field-programmable disk array signal processor for ultra-fast
signal processing was reported. The key contribution of the work is that a completely new photonic
chip architecture using optical micro-disk resonators (MDRs) as the fundamental execution units to
route, store and process optical signals is proposed. This chip architecture opens up a new
avenue for the implementation of a programmable photonic signal processor and creates more functionalities and
better performance. Thanks to the nature of ultra-compact size, strong wavelength selectivity and high
optical-confining capacity of MDRs, the proposed photonic signal processor features high scalability,
strong parallel computing capability, instant reconfigurability, and low power consumption.

April 2019: our work on programmable photonic integrated
waveguide Bragg gratings for optical and microwave signal processing was highlighted in IEEE
Photonics Society Newsletter in its 2019 April issue. Fiber Bragg gratings since the invention
over 30 years ago by Hill et al in the Communications Research Center Canada have been
extensively employed for various applications such as optical filtering, dispersion compensation,
distributed fiber-optic sensing, and microwave photonic signal processing. The major limitation of
a fiber Bragg grating is its limited reconfigurability. Once fabricated, the spectral response
can be hardly tuned or with limited tunability via temperature or mechanical tuning.
On the other hand, Bragg gratings implemented on a silicon-on-insulator (SOI) platform
can be electrically reconfigured at an ultra-fast speed, which can be employed for
high-speed programmable photonic signal processing.

(PPT).

equivalent-phase-shifted waveguide Bragg grating for multichannel signal processing was reported at OFC2019 in San Diego, USA.

is easier to fabricate with much smaller fabrication errors (PPT).

-
June 2018: our work on
Parity-Time Symmetry Optoelectronic Oscillator was published in Science Advances in the June 2018 issue.
In the work, a new concept "Parity-Time Symmetry" is introduced, for the first time,
to the field of Microwave Photonics. The key importance of the concept in microwave photonics
is that it enables the implementation of an optoelectronic oscillator for single-frequency
and ultra-low phase noise microwave generation without the need of an ultra-narrow optical
or microwave filter. This is the very first demonstration that such a concept is successfully
employed in a microwave photonic system. The employment of Parity-Time Symmetry in an
optoelectronic oscillator overcomes the long existing mode-competition and mode-selection
challenge which has severely limited the development and wide applications of optoelectronic oscillators.

temporal differentiation, microwave time delay, and frequency identification. The availability of
ultrafast and reconfigurable gratings opens new avenues for programmable optical signal
processing at the speed of light.
