Utilization of Optical Coherence Tomography for Retina Study: From Realistic Phantoms to Preclinical Evaluation in Rodents and Marmosets
This presentation discusses the comprehensive utilization of Optical Coherence Tomography (OCT) in advanced retinal research, spanning from system calibration to preclinical evaluation. We introduce a 13-layered "Super Phantom" that replicates the human retina's characteristics, providing a reliable benchmark for multimodal imaging standardization. Furthermore, we demonstrate the platform’s utility through collaborative research with Seoul National University Hospital, where our high-resolution OCT system was employed to validate adenine base editing therapies in RS1-mutant mouse models. By capturing precise in-vivo images across diverse species, including marmosets, this study establishes a robust framework for consistent retinal assessment and highlights the versatility of our imaging platform in supporting cutting-edge therapeutic developments.

Scalable Heterogeneous Integration for Next-Generation Nanophotonics
This presentation introduces recent advances in transfer-integrated nanolaser platforms for next-generation silicon photonics and co-packaged optics (CPO). Starting from planar heterogeneous integration of III–V nanolasers onto silicon waveguides, scalable transfer-printing strategies for ultra-compact on-chip light sources will be discussed. Particular emphasis will be placed on rolling-enabled non-planar integration, which introduces mechanical orientation as a new degree of freedom for polarization-selective coupling and expanded device functionality. In addition, minimal-gain printed silicon nanolasers enabling continuous-wave operation and three-dimensionally programmable nanolaser arrays around optical fibers will be presented, demonstrating how transfer integration can extend nanophotonic systems beyond the limitations of conventional monolithic fabrication.

Advances in 3D OCT Metrology using Wavelength-Swept Lasers
Optical coherence tomography (OCT) is a non-invasive imaging modality capable of providing high-resolution, three-dimensional visualization for both biomedical and metrological applications. Compared to classical time-domain OCT (TD-OCT), swept-source OCT (SS-OCT) offers faster imaging speeds and a better signal-to-noise ratio due to advancements in wavelength-swept laser (WSL) light sources. The performance and application range of a WSL are primarily determined by the laser’s linewidth, tuning range, linearity, and repetition rate. This presentation reviews the development and current status of WSL light sources and their imaging applications, with a focus on achieving higher speeds and improved precision in 3D metrology.
Chang-Seok Kim obtained his Ph.D. in 2004 from the Department of Electrical and Computer Engineering, Johns Hopkins University, USA, for research in the area of biomedical imaging and fiber laser systems, after finishing his Master's degree in 1999 from Gwangju Institute of Science and Technology (GIST) and his Bachelor degree in 1996 from Korea Advanced Institute of Science and Technology (KAIST), Korea. Subsequently, he held a postdoctoral fellowship at the Beckman Laser Institute and Medical Clinic, University of California at Irvine, USA, for research in the area of biophotonics and biomedical sensing. He returned to the Department of Optics and Mechatronics Engineering, Pusan National University, Korea as a faculty member in 2005 and is now a Professor.
His early research covered specialty fiber design/fabrication and fiber lasers. Following his initial wide experience with fundamentals in fiber optics, his research interests have moved to applications of wavelength-tunable fiber laser. Nowadays, his research has diverged to the practical system for 3D biomedical and metrological imaging applications based on wavelength-tunable fiber lasers, such as optical coherence tomography (OCT) imaging, photo-acoustic tomography (PAT) imaging, and FMCW (frequency modulated continuous wave) light and detection and ranging (LIDAR) imaging. His work has led to over 180 SCI journal publications and 50 registered patents.

Advances in Optical Fiber Sensing Systems Based on Wavelength-Swept Lasers
Recent advances in optical fiber sensing systems based on wavelength-swept lasers (WSLs) are presented. An ultra-wideband WSL with a scanning bandwidth exceeding 440 nm enables one-to-one mapping between spectral and temporal domains, allowing real-time interrogation without complex signal processing. This approach is applied to strain sensing using cholesteric liquid crystal elastomers and to volatile organic compound detection using porous cholesteric liquid crystal films integrated on fiber ferrules. The results demonstrate high sensitivity, fast response, and stable operation, indicating the suitability of WSL-based systems for practical real-time optical sensing applications.
