Amplitude noise suppression by intracavity phase modulation in a harmonically mode-locked laser
Ozharar, Sarper; Ozdur, Ibrahim (ELSEVIER SCI LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, OXON, ENGLAND, 2018)A fiber coupled semiconductor ring laser that employs both an amplitude and a phase modulator was built and actively harmonic mode-locked at a repetition rate of 10 GHz. The phase modulator was driven at the cavity fundamental ... -
The Effects of Intracavity Phase Modulation and Extracavity Optical Filtering on Amplitude Noise of Mode-Locked Pulse Trains
Ozharar, Sarper; Ozdur, Ibrahim (IEEE, 345 E 47TH ST, NEW YORK, NY 10017 USA, 2018)An actively mode-locked, fiber-coupled semiconductor ring laser that employs both a phase modulator and an amplitude modulator was built. The laser was mode locked by loss modulation at 10 GHz and the intracavity phase ... -
Experimental analysis of absolute phase noise of a harmonically mode-locked semiconductor laser
Ozharar, S.; Ozdur, I. (NATL INST OPTOELECTRONICS, 1 ATOMISTILOR ST, PO BOX MG-5, BUCHAREST-MAGURELE 76900, ROMANIA, 2018)In this work, we have designed and experimentally characterized the absolute phase noise of a fiber coupled semiconductor ring laser at 1550 nm, actively mode-locked at 10 GHz by an external RF oscillator. The dependency ... -
Multifunction optoelectronic gate
Ozdur, Ibrahim Tuna; Ozharar, Sarper; Delfyett, Peter J. (WILEY, 2015)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 ... -
Optical detection of microplastics in water
Iri, Ahmet H.; Shahrah, Malek H. A.; Ali, Ali M.; Qadri, Sayed A.; Erdem, Talha; Ozdur, Ibrahim T.; Icoz, Kutay (SPRINGER HEIDELBERGTIERGARTENSTRASSE 17, D-69121 HEIDELBERG, GERMANY, 2021)Unfortunately, the plastic pollution increases at an exponential rate and drastically endangers the marine ecosystem. According to World Health Organization (WHO), microplastics in drinking water have become a concern and ... -
Performance analysis of photonic lantern based coherent receivers
Oran, A.; Ozdur, I. (NATL INST OPTOELECTRONICS, 1 ATOMISTILOR ST, PO BOX MG-5, BUCHAREST-MAGURELE 76900, ROMANIA, 2018)In this paper, we present the simulation results for bit-error-rate improvements of photonic lantern based coherent LIDAR systems. Our results show that using a 19-port photonic lantern, the bit-error-rate can be improved ... -
Performance improvements of photonic lantern based coherent receivers
Ozdur, Ibrahim Tuna; Toliver, Paul; Woodward, T. K. (IEEE, 2014)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 ... -
RF phase noise filtering properties of an actively mode-locked laser
Mbonde, Hamidu; Ozharar, Sarper; Ozdur, Ibrahim (WILEY, 111 RIVER ST, HOBOKEN 07030-5774, NJ USA, 2018)In this article, we are presenting the experimental results and theoretical analysis of radio frequency (RF) phase noise filtering properties of a high Q cavity actively driven mode-locked laser. The experimental results ... -
Use of laser-induced bubbles in intraocular pressure measurement: a preliminary study
Altindis, Fatih; Ozdur, Ibrahim T.; Mutlu, Sait N.; Yilmaz, Bulent (IOP PUBLISHING LTD, TEMPLE CIRCUS, TEMPLE WAY, BRISTOL BS1 6BE, ENGLAND, 01.01.2019)This work investigates the feasibility of a novel approach for measuring intraocular pressure (IOP) by analyzing micron-level laser-induced bubble characteristics in the intraocular fluid. We believe that this concept may ...
