| Research Abstract |
We studied optical devices or optical integrated circuits with silicon and silica materials. We proposed hybrid silicon/silica integrated optical circuits, and demonstrated the excellent performance by both theoretical analysis and experiments. We also studied grating couplers that input/output optical signal to/from the circuits, and derived the design for compact and high coupling efficiency. We further studied the method of flip-chip mounting of laser diodes on the circuits, and demonstrated a tunable wavelength laser with the method.
