Optical coherence tomography (OCT) is a non-invasive optical imaging modality that can acquire subsurface images of biological samples in both two and three dimensions. OCT is being widely used in ophthalmology, where it provides structural images of the retinal layers that cannot be obtained by any other imaging method. While OCT is being used in many hospitals around the world, costs and complexity are still prohibitive for widespread application in existing and novel areas. Current implementations of OCT systems are commonly based on fiber and free-space optical components. Photonic integration of optical components on a wafer-level has shown advantages in cost, size, stability and power efficiency.
In the scope of this thesis, the student will design and simulate broadband integrated photonic components suitable for OCT. These components will be splitters, edge couplers, grating couplers and interferometers. If successful, the designs can be used in a European project where the goal is to create a hand-held OCT device that will be tested for retinal imaging. During the design process the student will learn about optical coherence tomography and master the widely used integrated photonics design package Lumerical. The work will also include some Python scripting.
