Photonic IC Lab.

Photonic Integrated Circuit (PIC) Laboratory focuses on the design, fabrication, and characterization of integrated photonic devices based on optical waveguide platforms. By leveraging semiconductor fabrication processes, various functional optical components are monolithically integrated on a single substrate to realize compact, high-performance photonic systems.

In our research, PIC devices are fabricated at the wafer level, followed by device packaging and experimental validation through electrical and optical characterization. Compared to conventional free-space optical systems composed of discrete components, PIC-based implementations offer significant advantages in terms of miniaturization, robustness against environmental perturbations, and enhanced system stability.

The primary research objective of the laboratory is to translate free-space optical systems into fully integrated PIC architectures. Current research topics include optical phased array (OPA)-based LiDAR sensors, fiber-optic current sensors utilizing the Faraday effect, and wavelength-tunable lasers based on Bragg grating structures.
