IS14 – Tunable optical mode converter based on SOI asymmetric channel waveguides

IS14 – Tunable optical mode converter based on SOI asymmetric channel waveguides

Younis B. M., Esamil M. S. M., Hameed M. F. O., Obayya S. S. A.

An optical mode converter based on asymmetric dual channel waveguides is reported and analyzed. The first channel is infiltrated with nematic liquid crystal (NLC) material while the second one has BK7 glass core. The first higher order mode of the NLC core is coupled to the fundamental mode of the neighboring core with high coupling […]

NM07 – Early Cancer Detection by Plasmonic PCF Sensor

Abdelghaffar M., Gamal Y., Soliman W., Badr Y., Hameed M. F. O., Obayya S. S. A.

Great research work has been studied for cancer detection due to its high death rate. In this paper, a novel design of photonic crystal fiber (PCF) biosensor based on surface plasmon resonance (SPR) is introduced and numerically analyzed for cancer cell detection. Full vectorial finite element method (FVFEM) is used throughout the numerical analysis of […]

NM14-Mid-infrared optical modulator based on D-shaped PCF

NM14-Mid-infrared optical modulator based on D-shaped PCF

Younis B. M., Yazeed N., Usama E., El-Sayed B., Almoqadem M. H., El-Sonbaty M. A., El-Shawadfy A., Abd-Elaziz A., Mahmoud S., Hameed M. F. O.,

Recently, photonic crystal fibers (PCFs) have become of compelling interest due to their diverse applications, especially in the mid-infrared (mid-IR) wavelength regime. In this work, an optical mid-IR modulator based on D-shaped PCF with germanium-antimony-tellurium (GST) as a phase-changing material (PCM) is presented and analyzed. Because of the phase transition of the GST material between […]

P16 – Plasmonic Dual D-shaped PCF Sensor for Low Refractive Index Applications

P16 – Plasmonic Dual D-shaped PCF Sensor for Low Refractive Index Applications

Gamal Y., Younis B. M., Hameed M. F. O., Obayya S. S. A.

Dual D-shaped (DD-shaped) plasmonic photonic crystal fiber (PCF) for refractive index sensing is designed and analyzed. In the proposed design, two gold nano-rods are attached to the two etched surfaces of the PCF to enhance the sensing characteristics. The surface plasmon (SP) modes excited at the metal/dielectric interfaces are strongly coupled to the PCF core […]

SC05 – Highly Efficient Dome Shaped Nanowires Solar Cell

SC05 – Highly Efficient Dome Shaped Nanowires Solar Cell

El-Bashar R., Hameed M. F. O., Obayya S. S. A.

The optical characteristics of Si dome-tapered nanowires (NWs) solar cell (SC) are reported and analyzed by using finite difference time domain method. The geometrical parameters are studied to maximize the light absorption and hence the ultimate efficiency and short circuit current density of the reported NWs SC. The dome-shaped NWs show better absorption enhancement than […]
