| Description | The aim of this work was to develop an all dielectric structure that could be used to collimate mid-infrared optical beams. Ultimately, such a structure could be incorporated into semiconductor lasers, which are used in applications such as environmental sensing. reducing the need to use complex and expensive optical systems to manipulate the laser beam. Simulations confirmed that it is possible to colllimate an optical beam using such a structure. A structure was then designed and tested, but the experimental results were less conclusive than the simulations. |
| Exploitation Route | Having shown the feasibility of using such a dielectric structure, other researchers can now optimise the structure design to allow an experimental demonstration, |
