Arda Şahin has been awarded TÜBİTAK 2209 support

Arda Şahin has been awarded TÜBİTAK 2209 support (research project supporting programme for university students) with his project called “Data Communication System Between Two Devices Through Visible Light Spectrum”.

The project is consulted by Dr. Kıvılcım Yüksel Aldoğan and aimed to enhance the performance parameters of a Li-Fi (Light Fidelity) prototype previously developed at the Department. Second aim of the project will be implementing a Medium Access Control to increase the number of users supported by the system.

February 2020

Our paper has been accepted for a poster presentation at the International Conference on Optical Fiber Sensors (OFS 2020)

Combined Effect of Multi-Reflection and Spectral Shadowing Crosstalk in Phase-OTDR System Using Fiber Bragg Grating Array. 

The multi-reflection crosstalk when combined with the spectral-shadowing effect has been shown to make the interpretation of spectral analysis more difficult in Phase-OTDR sensing system based on weak fiber Bragg grating array.

The International Conference on Optical Fiber Sensors (OFS), established in 1983, is acknowledged as the world’s leading conference on all topics related to photonic sensing technologies. OFS provides a forum for reporting and exchanging ideas on the latest advances in research and development on fiber-optic and photonic sensing.
