About the Laboratory & Research Area
Q-SPIN (Quantum Semiconductor Photonics and Integrated Nanophotonics) Laboratory aims to develop next-generation quantum technologies and optical information processing systems using semiconductor-based photonic devices and photonic integrated circuits. In particular, our research focuses on photonic quantum information processing and integrated photonics platforms, where photons serve as the fundamental carriers of information and computation.
Modern information technologies increasingly demand higher data processing speeds and improved energy efficiency. To address these challenges, photonics-based information processing and quantum technologies are emerging as promising alternatives to conventional electronics-based systems. In this context, our laboratory utilizes semiconductor-process-based photonic integrated circuits (PICs) as a core platform. By integrating various photonic components—such as light sources, detectors, modulators, and waveguides—onto a single chip, we develop complex photonic circuits and integrated quantum optical systems.
The research in our laboratory is broadly organized into three main directions.
￭ First, we develop integrated semiconductor light sources and quantum light sources. This includes silicon photonics-based semiconductor lasers, single-photon emitters based on two-dimensional materials, and integrated squeezed-light sources. Our goal is to realize CMOS-compatible light sources that can serve as key building blocks for next-generation photonic integrated circuits.
￭ Second, we study large-scale photonic integrated circuits for quantum optics and quantum information processing. By exploiting photon interference and entanglement, we investigate integrated photonic circuits capable of generating and manipulating quantum states of light, enabling scalable platforms for photonic quantum computing and quantum communication.
￭ Third, we explore high-speed optical information processing and optical interconnect technologies based on photonic integrated circuits. To address the growing data transmission demands of data centers and AI systems, we develop PIC-based optical interconnect technologies and practical photonic information processing platforms.
To pursue these research directions, our laboratory integrates a wide range of techniques, including photonic integrated circuit design, semiconductor fabrication, and both classical and quantum optical measurements. We also actively collaborate with domestic and international research institutions and industrial partners, with the goal of translating laboratory-developed technologies into practical applications in real-world industrial environments.
Ultimately, the Q-SPIN laboratory seeks to establish new paradigms in photon-based information technologies and to develop core hardware platforms for next-generation quantum technologies and optical information processing systems.
