Tunable Fiber Laser Source based on Supercontinuum Generation

The objective of the project is to conceive and build a prototype of a tunable “white fiber

laser” i.e. a broadband light source. As it is based on supercontinuum generation in a

microstructured fiber, the source is expected to be compact and find applications in several

domains, from fundamental studies to biomedical imaging and spectroscopy as well as

sensing. Current supercontinuum-based tunable sources use a straightforward design where

a tunable filter is used to select a narrow band of wavelengths from the broadband source,

discarding most of the light, thus being very inefficient. The project consists in conceiving and

building a more efficient tunable laser source. The idea is to extract a narrow band of

wavelength from the supercontinuum, and recycle the remaining supercontinuum in the same

fiber in a cavity. As a majority of the light will be recycled rather than discarded, the process

is expected to be more efficient than the current scheme.
