Full C-band wavelength-tunable, 250 MHz repetition rate mode-locked polarization-maintaining fiber laser
Autor: Yoon-Soo Jang, Jungjae Park, Jonghan Jin
Publikováno v: Scientific Reports, Vol 13, Iss 1, Pp 1-8 (2023)
Abstract We demonstrate a full C-band wavelength-tunable mode-locked fiber laser with a repetition rate of 250 MHz, representing the highest repetition rate for C-band tunable mode-locked lasers thus far to the best of our knowledge. The polarization

A novel method to design and evaluate artificial neural network for thin film thickness measurement traceable to the length standard
Autor: Joonyoung Lee, Jonghan Jin
Publikováno v: Scientific Reports, Vol 12, Iss 1, Pp 1-7 (2022)
Abstract The artificial neural networks (ANNs) have been often used for thin-film thickness measurement, whose performance evaluations were only conducted at the level of simple comparisons with the existing analysis methods. However, it is not an ea

A Hybrid Non-destructive Measuring Method of Three-dimensional Profile of Through Silicon Vias for Realization of Smart Devices
Autor: Heulbi Ahn, Jaeseok Bae, Jungjae Park, Jonghan Jin
Publikováno v: Scientific Reports, Vol 8, Iss 1, Pp 1-9 (2018)
Abstract Smart devices have been fabricated based on design concept of multiple layer structures which require through silicon vias to transfer electric signals between stacked layers. Because even a single defect leads to fail of the packaged device

Linear-cavity Er-doped fiber mode-locked laser with large wavelength tunability
Autor: Jungjae Park, Yoon-Soo Jang, Jonghan Jin
Publikováno v: Applied optics. 61(34)
A linear-type wavelength-tunable all-polarization-maintaining fiber mode-locked laser is proposed for the first time, to our knowledge, and is implemented with an Er-doped fiber and polarization-maintaining fiber components. The tuning range of the c
