Areas of specialization Optical Sciences,Optical Waveguide, Photonics, Nonlinear Optics, Polymer Optics, Biophotonics Sensors
Laboratory/research office Ultra-High Speed and Integrated Photonic Devices Laboratory
We have achieved low power consumption technology for ultra-high speed polymer modulators with an optical modulation bandwidth of 100 GHz. These polymeric modulators enable the realization of optical interconnection between integrated circuits, which supports increased signal communication speed and reduced power consumption, for application in future servers and personal computers.
We are also developing biophotonic sensors and networks of such sensors, based on optical waveguides doped with either green fluorescent protein or anti-body. The waveguides will eventually be connected with long-haul optical fibers that work as distributed and real-time sensors for the remote detection of dangerous chemicals such as sarin (i.e. for anti-terrorist defense) and harmful pandemic viruses. Networks for pandemic virus detection can be applied in immigration offices, airports, schools, and hospitals.
Current reseach topics 1. Ultra-high speed electro-optic polymer/TiO2 slot waveguide modulators
2. biophotonic waveguide sensors.
