The Laboratory

　

The laboratories of the optoelectronics group are located in rooms 303, 318-320 of the Ho Sin Hang Engineering Building. Research activitivies of the group concentrate mainly on components for fiber optic communications and ultrafast optoelectronic systems. Our research output have covered a wide range of topics including results on all-optical wavelength converters, reconfigurable add-drop switches, dispersion tuned lasers, high sensitivity autocorrelators based on two photon absorption in optical waveguides and terahertz detectors. Lists of recent publications from the group may be found at the homepages of Prof. K.T.Chan, Prof. C.Shu and Prof. H.K.Tsang.
