We work on broad range of topics from advanced passive devices for frequency and spatial domain light manipulation to complex integrated optoelectronic components with tailored material responses to allow light emission and light control in the temporal domain. Our group also strives to connect the state-of-the-art technologies with the real-world application by developing novel photonic devices.
Our research efforts can be categorized into the following topics:
Research technologies

Using an integrated AlGaAsOI microresonator, we demonstrate all-optical wavelength conversion of a high-speed data signal with low operation power at the sub-milliwatt level. Our work is a step towards a fully-integrated chip solution for high-speed optical signal processing.
