  • 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.
  • May 2018: Prof. Yao was awarded the 2018 R.A. Fessenden Award. Recipients of this medal are outstanding Canadian engineers recognized for their important contributions to the field of telecommunications engineering.
  • April 2018: our work on a fully reconfigurable waveguide Bragg grating for programmable photonic signal processing, was published in Nature Communications in the April 2018 issue. The major contribution of the work is the proposition of a novel structure of a silicon grating which can be fast reconfigured as a programmable signal processor to perform multiple signal processing functions including 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.

  • June 2017: Jiejun Zhang and Xiang Chen received their PhD degree certificates at the convocation of the University of Ottawa, held in the Shaw Centre on 20 June 2017.
  • May 2017: our work on an integrated parity-time symmetric wavelength-tunable single-mode microring laser was published in Nature Communications in the May 2017 issue. The key contribution of the work is that a monolithically photonic integrated parity-time symmetry wavelength-tunable single-mode microring laser was designed, fabricated and experimentally demonstrated. Stable and single-mode lasing without using an ultra-narrow band optical filter with a high sidemode suppression ratio exceeding 36 dB is demonstrated. The lasing wavelength is continuously tunable electronically with a tuning range of 0.22 nm.
