An article on "Dynamics of a Short Cavity Swept Source OCT Laser" by CAPPA researchers is the Feature of the Week on the OCTNews.org website. The site is a high-profile resource for the Optical Coherence Tomography community, collecting and highlighting significant publications and new products in the field. The website regularly selects a paticularly noteworthy article to be the Feature of the Week, displayed prominantly on the home page, with a slide show presentation to accompany the article.
The featured CAPPA article describes the group’s work on experimental characterisation and numerical modelling of a fast frequency swept laser source used in OCT. It describes the various lasing regimes (mode hopping, sliding frequency mode locking and chaos), explains their origin and uses the model to provide guidelines for further laser OCT performance optimisation.
The CAPPA researchers involved are Svetlana Slepneva, Ben O’Shaughnessy, Bryan Kelleher, Stephen Hegarty and Guillaume Huyet, and the work was performed in collaboration with the Nicolaus Copernicus University in Torun, Poland and the Weierstrass Institute in Berlin, Germany.
