Research

  • High speed SWIR/MWIR photodiodes

    High-speed short-wavelength infrared (SWIR)/mid-wavelength infrared (MWIR) have a wide range of applications in emerging areas such as free-space communications, 2 µm optics fiber communication, dual-frequency comb spectroscopy, chemical sensing, and LIDAR. Our group works on InP based on InGaAs/GaAsSb type-II superlattice for high-speed SWIR photodiodes applications, which enjoys the mature process technologies developed by InP-based fiber optics communications. In the MWIR region, our group mainly focuses on the InAs/InAsSb and InAs/GaSb type-II superlattice for high-speed MWIR detection.

  • High speed, high power photodiodes

    The recent explosive growth in communications has been brought about by fiber optic and wireless communications technologies. These two technologies have merged to create an interdisciplinary area called microwave photonics, including RF optical links, oscillators, and radar. The research in the Optoelectronic Devices Group at ShanghaiTech University focuses on developing optoelectronic components and technologies that enable new applications and advances in microwave photonic systems. One of the critical devices for signal generation in microwave photonic systems is the high-speed, high-power photodiode. Our work includes developing state-of-the-art Silicon-based, InP-based high-speed, high-power photodetectors and arrays.

  • Monolithic integration of III-V devices on silicon

    The vast majority of research on silicon photonics has focused on devices operating within near-infrared (NIR) telecommunication bands from 1310 nm to 1550 nm wavelength. It was driven by the low-cost photonics fabricated with existing complementary metal-oxide-semiconductor (CMOS) infrastructure and the large market for telecommunications with the ever-increasing demands. Our group works on the monolithic integration of III-V MWIR photonic devices on Silicon. These technologies can offer potentially high performance, high yield, and low-cost products, significantly reshaping the current mid-infrared market.
