Ehab Salaheldin Awad Mohamed: Three-dimensional space-division Y-splitter for multicore optical fibers. King Saud University, October 9, 2018: US10094980

The three-dimensional space-division Y-splitter for multicore optical fibers (MCF) is a 3-D device that depends on space-division splitting (SDS) by double-hump graded-index (DHGI) in a rectangular waveguide. It includes multiple single Y-splitters, each one being dedicated to one MCF core. Each Y-s ...

Ehab Salaheldin Awad Mohamed, Mohamed Ramy Abdel Rahman: Optical absorber for long-wave infrared radiation. KING SAUD UNIVERSITY, Richard C Litman, September 8, 2015: US09128230

The optical absorber for long-wave infrared radiation includes a nano-plasmonic gold structure arrayed on an absorbing dielectric substrate in an alternating checkerboard-type pattern. A plurality of plasmonic cells are formed on an upper surface of the absorbing dielectric substrate, which can be, ...
