Anomaly Detection of Underground Transmission-Line through Multiscale Mask DCNN and Image Strengthening
Autor: Min-Gwan Kim, Siheon Jeong, Seok-Tae Kim, Ki-Yong Oh
Publikováno v: Mathematics, Vol 11, Iss 14, p 3143 (2023)
This study proposes an integrated framework to automatically detect anomalies and faults in underground transmission-line connectors (UTLCs) with thermal images because anomaly detection of underground transmission-line connectors (UTLCs) plays a cri

A 66-GHz Lumped-EML Submodule Using Resistance-Optimized LC Resonance with Low Temperature Dependence of 3-dB Bandwidth
Autor: Seok-Jun Yun, Young-Tak Han, Dong-Hoon Lee, Dong-Hyo Lee, Seok-Tae Kim, Jang-Uk Shin, Sang-Ho Park, Seo-Young Lee, Yongsoon Baek
Publikováno v: Optical Fiber Communication Conference (OFC) 2023.
We report on a lumped-EML submodule with 3-dB bandwidths of 68.2 GHz at 25℃ and ~66 GHz at 70℃ using a resistance-optimized LC resonance effect, showing low temperature dependence and making it suitable for 112-Gbaud operation.

Color 3D display and security via monochrome scenes
Autor: Junfeng Guo, Yu Kou, Seok-Tae Kim, Xiaowei Li
Publikováno v: Optics Letters. 48:1570
Color three-dimensional (3D) displays have always been the ideal display method because of their strong sense of reality, whereas color 3D displays of monochrome scenes are still challenging and unexplored. A color stereo reconstruction algorithm (CS

Optical Subassembly Modules Using Light Sources Butt-Coupled With Silica-Based PLC
Autor: Seok-Jun Yun, Dong Hoon Lee, Seo-Young Lee, Sang-Ho Park, Yongsoon Baek, Jang-Uk Shin, Seok-Tae Kim, Young-Tak Han
Publikováno v: IEEE Photonics Technology Letters. 32:132-135
We have fabricated DML/EML-based subassembly modules based on chip-to-chip optical butt-coupling with straight waveguides between a silica AWG chip and commercial directly modulated laser (DML) or electro-absorption modulated laser (EML) chips. By pr

Realization of EML Submodule for 100-Gbaud Operation Using LC Resonance with Optimization of Load Resistance
Autor: Seok-Jun Yun, Young-Tak Han, Dong-Hoon Lee, Seok-Tae Kim, Min-Jun Kwak, Jang-Uk Shin, Sang-Ho Park, Seo-Young Lee, Yongsoon Baek
Publikováno v: Optical Fiber Communication Conference (OFC) 2022.
By using LC resonance effect with optimization of load resistance, the 3-dB bandwidth of a lumped-EML submodule can be enhanced to > 55 GHz although an EAM length is 150 um, making it enable 100-Gbaud operations.
