I am a researcher in the cloud systems futures Group at Microsoft Research Cambridge, UK. My research focus on solving the challenges of networking for next generation data center. I love the multidisciplinary environment at Microsoft. On one hand, I could contribute my previous research experience in photonic devices and optical communication systems to the projects. On the other hand, I could gain a lot of knowledge from colleagues who works on networking and application layers in the cloud.

Projects
In the past, I have worked on the following projects:
-
Exploiting the bandwidth potential of multimode optical fibres (COMIMO)
Before joining Microsoft Research, I worked as a Research Associate at the Opitcal Network Group at University Colleague London, UK for the COMIMO project (2012 - 2017). In this project, I have built a 10×10 mode division multiplexing system over a 24km ring core fiber in collaboration with University of Southampton and University of Central Florida with digital signal processing algorithms that I have developed to enable fast convergence rate and low complexity for the optical multiple-input and multiple-output (MIMO) system. We have manged to achieve a 1.12 terabit per second transmission rate over an single optical fiber.

During my PhD study and afterwards, a short period of post-doc experience at the Radio and Optical Communications Laboratory, Dublin City University, my research focuses on characterization and application of fast wavelength tunable lasers. I have developed a dynamic linewidth characterization method, where the transient laser phase noise after a switching event between two wavelengths can be accurately measured with a 1ns time step. This characterization is critical when the wavelength tunable lasers are used in a optical burst switching system using high order modulation format with coherent detection.
I have also characterized a novel three-section slotted Fabry Perot laser, which was developed by our collaborators at Tyndall National Institute. The characterization revealed the fundamental tuning mechanism of the device.
