PhD Studentship - Holographic Data Storage

University of Birmingham - School of Chemical Engineering

Competition Funded PhD Project (Students Worldwide)

Application Deadline: Applications accepted all year round

Supervisor: A.K. Yetisen

Project Description

The development of nanostructures that can be reversibly arranged and assembled into 3D patterns may enable optical tunability. However, current dynamic recording materials such as photorefractive polymers cannot be used to store information permanently while also retaining configurability.

This project aims to demonstrate the capability to organise nanoparticles into 3D assemblies in a recording medium using optical forces produced by the gradients of standing waves. The nanoparticles in the recording medium will be organised by multiple nanosecond laser pulses to produce reconfigurable slanted multilayer structures. The capability of producing rewritable optical elements will be demonstrated by producing multilayer Bragg diffraction gratings, 1D photonic crystals, and 3D multiplexed optical gratings. This recording strategy may have applications in reconfigurable optical elements, data storage devices, and dynamic holographic displays.

The successful student will form part of a multidisciplinary team and will be supervised by Dr. Ali K. Yetisen based in the School of Chemical Engineering at the University of Birmingham.

Funding Notes

Students must have an undergraduate degree or master’s degree in physics, engineering, chemistry, materials science or a closely related subject.

University of Birmingham scholarships are available for exceptional UK/EU students. Self-funded international students are welcome to apply this post. Potential candidates should contact Dr. Ali K. Yetisen (a.k.yetisen@bham.ac.uk) and include a CV. Applications will be evaluated on an on-going basis until the position is filled.
