Asmaa joined our group on 2015. She was requested to focus her study on silicon-based photonic crystals constructed from nanoporous silicon. During her M. Sc study, she used the photonic structure with variavble pore size for filtering application. Her Ph. D work was focusing on the utilization of one-dimensional silicon-based photonic crystals for omnidirectional mirrors applications. Omnidirectional mirrors have the ability to reflect the incident light over a range of wavelengths at all angles of incidence irrrespective of the type of polarization. She left our group on 2024.
