Jihwan and Dohun’s paper, “Polarization-Independent Directional Coupler Using Tilted Subwavelength Gratings,” has been published in the Journal of the Optical Society of America B! Congratulations!

This work started as the final project for our EE40042 “Introduction to Integrated Photonics” course and is a great example of how classroom work can grow into a journal publication. Great job! Link: https://doi.org/10.1364/JOSAB.612181

Kim group won the EE Graduate Futsal Tournament!

Our lab team, together with Prof. Jeong’s group, won the KAIST EE Graduate Futsal Tournament this week! ⚽🏆 Congratulations to the team! Healthy Body, Healthy Mind, Brilliant Research!

Jaewhan’s paper on “Strontium 1S0 → 1P1 transition frequency measurements assisted by a photonic grating chip” is published in Metrologia. Congratulations!

Mehedi’s paper on “Modeling method for concentric ring resonators with dispersion engineering” is published in Optics Express. Congratulations!

Lanxuan’s paper on “Time-lens-based optical phased array LiDAR for ranging and accuracy enhancement” is published in APL Photonics journal. Congratulations!

New Members! 🎉 Welcome Junyeol (MS/PhD), Jun Wang (PhD), Jungmyeong, Napol, Haeun, and Chaehun (Undergraduates)!

Sangsik, Jibaek, and Soomin presented our research at the OECC 2025 conference!

Taewon, our undergraduate URP student, recieved two poster awards! One from the 1st Optical Science & Opto-Semiconductor Workshop (OSW) and the other from the KAIST Optics Group students poster competetion. Good job!

A Review paper by Yoseph Shin titled “Anisotropic Metamaterials for Scalable Photonic Integrated Circuits: A Review on Subwavelength Gratings for High-Density Integration” has been published in Nanophotonics journal.

Please check out the areas of expertise we’ve developed over the past few years –  SWGs for high-density PIC integration! Link: https://www.degruyter.com/document/doi/10.1515/nanoph-2024-0627
