The Effect of Mode Area and Refractive Index for Optical TE Mode Propagation in Hybrid LN/Si Electro-Optic Structure of Mach-Zehnder Modulator

Luma Z Mohammed; Sarah M. Taleb; Makram A. Fakhri

Volume 20, Issue 4 , October 2020, , Page 71-77

  We propose and analyse a silicon based hybrid modulator on the nano thin film of the lithium niobate or commonly known as silicon-on-insulator technology. The Mach–Zehnder stripe optical waveguide of electro-optical modulator operats at GHz frequencies with large bandwidth and low losses between ...  Read More ...

Morphological and Optical Properties of Cu2O/ 2-D Silicon Photonic Structure for Sensing Applications

Mariam M. Hassan; Makram A. Fakhri

Volume 20, Issue 2 , April 2020, , Page 10-13

  In this paper the porous silicon (PS) was fabricated by photo electrochemical technique. Deposition of Cu2O thin film on nanocrystal-lines silicon by pulse laser was deposited by using the Tattoo removal laser, 2J and 1064 nm wavelength, and high purity Cu target at 350K in static air. Surface morphology ...  Read More ...

Optical and Structural investigations of LiNbO3 thin films by PLD

Sarah M. Taleb; Makram A. Fakhri; Salah Aldeen Adnan

Volume 20, Issue 1 , January 2020, , Page 16-23

  Lithium niobate (LiNbO3) nanostructure thin film was prepared and deposited on the substrates made of quartz by utilizing pulse laser deposition (PLD) technique. The effect of substrate temperature changing on the optical and structural properties of LiNbO3 films was investigated and studied. The chemical ...  Read More ...

Structural, Morphological and Optical Properties of Gold Nanoparticles Using Laser Ablation in Liquid for Sensor Applications

Zainab H. Tawfiq; Sarah A. Adnan; Makram A. Fakhri; Rihab K. Hamad

Volume 19, Issue 4 , October 2019, , Page 30-35


  The impact of laser wavelength on gold nanoparticle (Au NPs) creation isaccounted by the extraction of gold atoms from the gold specimen immersed in ethanol.Pulsed Laser ablation in fluid procedure of the gold target was carried out by employingNd:YAG laser (nanosecond pulses). Characterization of accomplished ...  Read More ...
