    This R&D project will develop a technology platform for optical sensors which can provide unique features such as compact size, fast response, cost effectiveness and enhanced functionalities. The technological challenges such as limited space for sensor implementation, high resolution readout, cost reduction and more functions have initiated technology development in two areas: micro optoelectronics packaging and signal modulation schemes. Based on these technologies, we will develop optical proximity sensor for smart home control and smart cell phones, distance sensor and tilt sensor for semiconductor manufacturing according to the requirements from industrial partners. Besides, we will also develop data cable with embedded optical link to provide a robust, EMI immune channel for sensing signal transmission. In order to achieve these targets, we will leverage ASTRI's photonic component domain knowledge in fiber optic transceiver development. This project can deliver high quality technology to Hong Kong industry and improve our local industrial partners’ competitiveness in the world market.
