Holography for Diffractive Optical Elements

This research domain focuses on the study of Holographic Optical Elements. Diffractive Optical Elements (DOEs) have been in development for many years and are an exciting technology  with the capability to re-direct light using diffraction rather than refraction. Applications include devices for pattern generation, beam splitting and demonstrate that in layers just microns thick, DOE’s can achieve light focusing, bending, reflection, beam shaping, beam splitting and combinations of these

Holographic Optical Elements (HOEs) are a subset of diffractive optical elements for which the photonic structure is created holographically, i.e. by recording a specific, controlled interference pattern in a suitable photosensitive optical material. They have two key advantages. Firstly, Volume HOEs can approach 100% efficiency in the diffracted beam due to Bragg diffraction, providing the possibility of HOEs that replace their refractive counterparts in a wide range of optical systems. Secondly, optical patterning allows for customization; volume photosensitive materials and production technologies have now developed to the point where the production of bespoke diffractive/holographic optical elements and films are finally within reach. This will open the door to practical applications for HOEs in everyday life.

We have in-house expertise in designing,  fabricating and manufacturing holographic elements, including the optical patterning systems and the photosensitive coatings and films needed. We are keen to expand our existing network of international researchers and commercial partners who have expertise or interests in these or related fields.
