Silicon photonics: novel group-IV photonic materials and devices
矽光技術: 新穎IV-IV族光電材料及元件
Silicon photonics is a powerful technology to ultimately minimize photonic systems and realize complex and functional photonic integrated circuits. The key is to overcome the indirect bandgap of group-IV semiconductors for developing efficient photonic devices. Our group focus on the development of group-IV direct-bandgap SiGeSn materials systems for novel Si-based photonic devices. By adding Sn into Ge using low-temperature molecular beam epitaxy, the bandgap can be transferred to direct, thus suitable for photonic devices. We have demonstrated several the world’s first novel GeSn-based photonic devices, including light-emitters, optical modulators, and photodetectors, and we are one of the world-leading research team in the field of silicon photonics.

Mid-infrared (MIR) region in the spectral range of 1.8-5mm is an important region for wide-spectrum applications including optical communication, bio-medical detection, Lidar sensing, and spectrometry. Here we focus on the development of novel Si-based photonic devices for MIR applications. With the unique benefits of CMOS compatibility, our Si-based photonic devices can be monolithically integrated with Si circuity for novel applications.

Optical biosensors and systems
光學式生物感測器及系統
Optical biosensors with unique advantages of high sensitivity and label-free are particular suitable for bio-medical detection and clinic diagnosis. The challenges are to realize cost-effective, sensitive, and rapid optical biosensors. Our research group focus on the development of inject-molded optical biosensors. Using nano-injection-molded techniques, we have developed novel, disposable, low-cost guided-mode-resonance optical sensors. We have also developed novel cost-effective intensity-detection-based systems to form novel optical biosensing systems for clinic diagnosis, point-of-care and personalized and precision medicine.
