Advanced Semiconductor Devices and Systems Lab

Our lab aims for advanced semiconductor devices/sensors and systems thereof. Our research interests include spanned from photodiodes/photodetectors to single-photon detectors/sensors, concentrating since 2006 on CMOS-compatible avalanche photodetectors (CMOS-APDs), single-photon avalanche diodes (SPADs), and silicon photomultipliers (SiPMs), along with their applications(e.g., LiDAR (light detection and ranging), D-ToF (direct time of flight), 3D vision, biophotonics, quantum photonics, space, security, silicon photonics, optical interconnects, etc.).

We are currently focusing more on the research and development of high-performance SPAD/SiPM/APD detectors/sensors for next-generation applications like:

(i) LiDAR/ToF sensors & applications: ADAS (advanced driver assistance systems), eventually for autonomous vehicles, robots, drones, unmanned aerial vehicles (UAVs), submarine/airborne/satellite LiDAR, machine vision, industrial automation, etc. and mobile devices for 3D face/gesture recognition/tracking, depth imaging, biometric authentication, AR/VR/MR/XR (augmented/virtual/mixed/extended reality), etc.

(ii) Biomedical applications: TOF PET (time-of-flight positron emission tomography), X-ray, SPECT (single-photon emission computed tomography), FLIM (fluorescence-lifetime imaging microscopy), super-resolution microscopy, NIRI (near-infrared imaging), PCR (polymerase-chain-reaction), ELISA (enzyme-linked immunosorbent assay), etc.

(iii) Safety and security: Night vision, low-light imaging, security cameras, radiation detectors, gamma cameras, dosimeters, cargo scanners, environmental monitoring, etc. 

(iv) Quantum applications: Integrated photonic quantum technology, Integrated photonic quantum detector, QKD (quantum key distribution), quantum communication, QRNG (quantum random number generators), quantum cryptography, optical quantum computing, etc.

(v) More applications wherever single-photon sensitivity and high precision time-of-arrival detection are critical.
