Experimental Analysis of Non-linear Phenomena due to Perturbation Amplitude in φ-OTDR Based Fiber Optic Distributed Vibration Sensor
(Optica Publishing Group (formerly OSA), 2020) Uyar, Faruk; Kartaloǧlu, Tolga; Ozbay, Ekmel; Ozdur, Ibrahim Tuna; AGÜ, Mühendislik Fakültesi, Elektrik - Elektronik Mühendisliği Bölümü; Ozdur, Ibrahim Tuna
We experimentally analyze the non-linearity effect due to the perturbation amplitude in the φ-OTDR based fiber optic distributed vibration sensor by investigating the effects of large disturbance signal.
Multifunction optoelectronic gate
(WILEY, 2015) Ozdur, Ibrahim Tuna; Ozharar, Sarper; Delfyett, Peter J.; 0000-0001-6452-0804; AGÜ, Mühendislik Fakültesi, Elektrik - Elektronik Mühendisliği Bölümü; Ozdur, Ibrahim Tuna
A multifunction optoelectronic gate that can perform as any desired logic gate of two variables was theoretically proposed and a simplified version is experimentally demonstrated. The proposed optoelectronic gate is dynamically configurable, and being wavelength independent, it can act on multiple input optical bits and realize different functions simultaneously.
Performance Analysis of Specialty Fiber Optic Cables for Distributed Acoustic Sensing
(Optica Publishing Group (formerly OSA), 2020) Uyar, Faruk; Kartaloǧlu, Tolga; Erol, Mustafa; Özbay, Ekmel; Ozdur, Ibrahim Tuna; 0000-0001-6452-0804; AGÜ, Mühendislik Fakültesi, Elektrik - Elektronik Mühendisliği Bölümü; Ozdur, Ibrahim Tuna
In this work, we present the signal-to-noise ratio comparison results of six different buried fiber optic cable for identical external perturbations using a home-made direct detection φ-OTDR system.
Performance improvements of photonic lantern based coherent receivers
(IEEE, 2014) Ozdur, Ibrahim Tuna; Toliver, Paul; Woodward, T. K.; 0000-0001-6452-0804; AGÜ, Mühendislik Fakültesi, Elektrik - Elektronik Mühendisliği Bölümü; Ozdur, Ibrahim Tuna
In this work, the signal-to-noise ratio improvement of photonic lantern-based coherent receivers over single-mode coherent receivers is demonstrated. The signal-to-noise ratio is improved by a factor of 2.8 when other parameters kept constant.
