معرفی
Hammad Ahmed serves as a Researcher at Heriot-Watt University's Institute of Photonics and Quantum Sciences within the School of Engineering & Physical Sciences, specializing in advanced optical device engineering and light manipulation.
His research expertise spans Optics and Photonics, with core focus areas in metasurface design, orbital angular momentum manipulation, and polarization-controlled structured light. He pioneers flat-optics solutions for generating complex beam profiles including vortex arrays and multispectral polarization cages, enabling breakthroughs in high-capacity optical communications and quantum information systems.
Recent publications (2025) reveal three dominant research trajectories: (1) Engineering multicolored orbital angular momentum combs for spectral multiplexing, (2) Developing dispersion-engineered metasurfaces using Debye relaxation models, and (3) Creating cascading polarization architectures for optical trapping applications. These works consistently leverage nanophotonic structures to achieve unprecedented control over light's spatial and spectral properties.
His collaborative network includes key researchers like X. Chen and M. A. Ansari, with publications appearing in Light: Science and Applications, Nano Letters, and Laser and Photonics Reviews. Current projects focus on enhancing orbital angular momentum sorter detection capabilities and developing wavelength-selective polarization digital systems for next-generation optical processors.
