Absolute phase noise analysis of a harmonically modelocked semiconductor laser
Ozharar, Sarper; Ozdur, Ibrahim (Optica Publishing Group (formerly OSA), 2017)We have designed and built a fiber coupled semiconductor laser at 1550 nm, which is harmonically mode-locked at 10 GHz by an external RF oscillator. The absolute phase noise of the laser is measured and discussed for two ... -
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 ... -
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 ... -
RF injection locked 18 GHz regeneratively mode-locked semiconductor laser
Oran, Abdullah; Ozharar, Sarper; Can, Gokhan; Olcer, Ibrahim; Ozdur, Ibrahim (OPTICAL SOC AMER, 2010 MASSACHUSETTS AVE NW, WASHINGTON, DC 20036 USA, 2018)In this manuscript, a semiconductor based fiber ring cavity mode-locked laser regeneratively driven at 18 GHz is presented. The optical spectrum of the laser is centered at 1578 nm. The laser is RF injection locked via an ... -
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 ... -
Simultaneous low noise radio frequency tone and narrow linewidth optical comb generation from a regeneratively mode-locked laser
Ozdur, Ibrahim; Ozharar, Sarper; Delfyett, Peter J. (SPIE-SOC PHOTO-OPTICAL INSTRUMENTATION ENGINEERS, 1000 20TH ST, PO BOX 10, BELLINGHAM, WA 98225 USA, 2014)A regeneratively mode-locked laser with simultaneous low noise radio frequency (RF) tone and optical comb generation is presented. The laser does not need any external RF signal and emits a pulse train at similar to 10 GHz ...
