Research Interests
Hon Tsang
obtained a PhD from Cambridge University on IIIV semiconductor waveguides
devices and their nonlinear optical properties in 1991. He joined CUHK in 1993 and shortly
thereafter branched out into the then
emerging field of silicon photonics. From its small beginnings
attracting interest from only a handful of groups, silicon photonics has grown
in the last 20 years to become a mainstream technology for high
speed energy efficient communications. It is emerging as a key technology for
optical interconnects in data centers, with large volume silicon photonic
products being manufactured by companies such as Intel.
Despite
the commercial silicon photonics transceiver products now being widely
available, silicon photonics still remains a fruitful topic for research
because there remains many important potential future
applications as energy efficient
onchip optical interconnects in high performance computers, low cost
labonachip gas sensors and integrated biosensors, and integrated quantum
photonic devices for quantum computing and quantum communications. Hon Tsang
has made fundamental contributions on the understanding of nonlinear properties
of guided wave optics in silicon waveguides, having carried out some of the
first studies of optical nonlinearities in silicon optical waveguides. As an R&D director in Bookham
Technology plc, in the early 2000s he led the development team for the silicon
waveguide variable optical attenuator arrays which were deployed
commercially in telecommunication networks. Those early silicon photonic products
enabled dynamic balancing of optical power levels during the reconfiguration of
Wavelength Division Multiplexed (WDM) networks.
Hon
Tsang’s research on the interrelationships between two photon
absorption, free carrier absorption and nonlinear refraction, led to the
experimental realization of high net gain optical amplifiers based on
stimulated Raman scattering in silicon waveguides. These papers are
increasingly relevant in the design of silicon nanophotonic integrated circuits
because the tiny crosssectional areas of these silicon waveguides enable
nonlinear optical effects such as two photon absorption or selfphase
modulation to manifest at optical powers as low as a few milliwatts. Hon
Tsang’s current research topics include:
·
Subwavelength
gratings for steering, coupling, switching, filtering
light in the spatial, spectral and polarization domains
·
Silicon photonics for
energy efficient terabit/s optical communications
·
Integrated quantum
photonics for quantum imaging
·
Hybrid integration
of 2D materials (such as graphene,
MoS_{2}, WS_{2} WSe_{2} , hBN etc) for photodetectors, modulators and nonlinear photonics
·
Integrated photonics
for 3D imaging and optical coherence tomography
