Main Research Topics
1. Coherent III-V light source for Si-Photonics
1) III-V lasers directly grown on on-axis (001) silicon
2) Ultra-Reliable Quantum Cascade Laser directly grown on mismatched substrate
Silicon photonics, based on its compatibility with existing CMOS processes, enables low-cost and large-scale production, while realizing high-speed data transmission and low-power devices, making it a key technology for next-generation communication and data center systems.
EPiLab conducts in-depth research on realizing reliable III-V light sources compatible with CMOS processes, which is one of the major challenges in silicon photonics.
2. Single Photon Source / Single Photon Detector
1) III-V Quantum Dots
2) III-V Avalanche Photodiodes for Single Photon Detection
Single-photon generation and detection are essential components in quantum technologies such as quantum communication, quantum cryptography, and quantum computing, as they enable precise control of quantum states and highly reliable information transmission.
One of the main research topics currently being pursued in EPiLab involves single-photon generation using III-V-based quantum dots, as well as the development of ultra-sensitive photodetectors based on III-V materials capable of detecting single photons with high efficiency
3. Reliable and Efficient Red/Amber microLEDs
1) Virtual Substrate with Engineered Lattice Constant
Red and amber microLEDs are essential components for the commercialization of microLEDs, which are core elements of next-generation displays. Their efficient implementation plays a critical role in enhancing color reproduction and energy efficiency, particularly in realizing high-resolution and high-brightness displays.
EPiLab is dedicated to developing novel epitaxial structures and device fabrication processes to achieve reliable and high-efficiency red and amber microLEDs.
