PhD Project: Time Stretched Pulse Supercontinuum (SPSC) swept laser source

During the last years, the progress in All-Normal Dispersion (ANDi) fiber manufacturing lead to a new technique to generate low-noise supercontinuum sources. These broadband lasers can be used in Optical Coherent Tomography (OCT) systems to get high resolution and high sensitivity imaging. Another technique called time-stretch allows overcoming one of the bottlenecks of OCT: the lack of high speed, high sensitivity detector and digitizers. In this project, we aim to build low noise, near-visible IR sources that combine the strength of the ANDi Supercontinuum and Time Stretch to improve the capabilities of OCT systems.
