Dr. Yüksel Selected for List of Top-Cited Scientists
Dr. Yüksel listed on Stanford University’s list of the world’s most influential scientists (on the single recent year impact list, 2023) due to her impactful international publications in Optoelectronics & Photonics, Enabling & Strategic Technologies.
The Updated Science-wide Author Databases of Standardized Citation Indicators, compiled annually by Prof. John P.A. Ioannidis and his team at Stanford University, aim to bring together the world’s most influential scientists. This list is prepared by considering indicators including number of publications, citations, h-index, and hm-index. While the career-long metrics honor researchers who have consistently demonstrated exceptional performance over time, the single recent-year metrics highlight researchers who have gained significant attention more recently. H-index is a metric representing the number of citations for a researcher’s most-cited publication. Hm-index is a metric that, by weighting citations, highlights a researcher’s more impactful works.

IZTECH Scientific Project Kick-off Meeting
Project Title: Optimization of Heat Transfer with Food Quality Criteria in Food Thawing Process by Pulsed Radio Frequency
In the proposed project, it is aimed to perform the minimum thawing time and minimum quality losses with RF technology, which is an innovative and fast thawing technique. Thawing of foods is a process with a high potential to create problems in terms of food safety. Especially in restaurants, food factories, workplace/school/hospital cafeterias, since meals are prepared for crowded groups, the issue of food safety is very important and it is preferred that the thawing process be carried out in the most reliable and fast way in these businesses. With the RF device to be designed with the proposed project, a device that will be very useful for the sectors in question will be designed to perform the thawing process in a short time and with high safety.
Our Lab will be collaborating with the researchers from Mechanical Engineering and Food Engineering Departments.

New paper published in Applied Optics
Intensity and phase stacked analysis of a Φ-OTDR system using deep transfer learning and recurrent neural networks
In this study, a two-stage feature extraction methodology that combines the capabilities of these neural network architectures with transfer learning is proposed to classify vibrations applied to an optical fiber by a piezoelectric transducer. First, the differential amplitude and phase information is extracted from the phase-sensitive optical time domain reflectometer.
Phase-OTDR recordings and stored in a spatiotemporal data matrix. Then, a state-of-the-art pre-trained CNN without dense layers is used as a feature extractor in the first stage. In the second stage, LSTMs are used to further analyze the features extracted by the CNN. Finally, a dense layer is used to classify the extracted features. To observe the effect of different CNN architectures, the proposed model is tested with five state-of-the-art pre-trained models (VGG-16, ResNet-50, DenseNet-121, MobileNet, and Inception-v3). The results show that using the VGG-16 architecture in the proposed framework manages to obtain a 100% classification accuracy in 50 trainings and got the best results on the phase-OTDR dataset. The results of this study indicate that pre-trained CNNs combined with LSTM are very suitable to analyze the differential amplitude and phase information represented in a spatiotemporal data matrix, which is promising for event recognition operations in DAS applications.

New paper published in Optical Fiber Technology
In this paper, the parasitic components (i.e., multi-reflections, Rayleigh scattering, photodetector noise, and phase variations due to external perturbations) are analysed and based on this analysis, a new signal to noise ratio (SNR) definition is provided suitable for the FBG-assisted Phase-OTDR system. A detailed analysis of performance parameters in the presence of multi reflection crosstalk (including its first- and second-order components) and spectral shadowing crosstalk is presented. SNR was calculated for different reflectivity and spacing lengths showing that the maximum number of cascaded FBGs can be significantly increased by using lower FBG reflectivity.
It was also observed that the spacing length distance does not have a significant impact on the maximum number of FBGs that can be interrogated. By comparing single-pulse and double-pulse configurations, the use of double pulse was shown to provide higher SNR values when the number of FBGs is around 100 FBGs. The multi-reflection crosstalk when combined with the spectral-shadowing effect was demonstrated to create secondary crosstalk components making the interpretation of spectral analysis more difficult.

New paper published in Optical Fiber Technology
Current Sensing Using a Phase-Sensitive Optical Time Domain Reflectometer: Feasibility Study
A novel method for distributed current sensing using an FBG-assisted Phase-OTDR with Mach-Zehnder Interferometer is proposed. The detrimental effect of the intrinsic linear birefringence of the sensing fiber is solved by calibration. An FBG pair is written at the two ends of the spun fiber coil to eliminate phase fading and increase the measurement accuracy. A simulation tool was developed to reveal the feasibility of the approach by investigating the impact of the detector noise as well as the effects of bending- and FBG-induced linear birefringence on the sensing performance.
