Using a hair-thin optical fibre, the researchers can look into deep brain areas of a living mouse as if through a keyhole. Recently introduced methods for holographic control of light propagation in complex media enable the use of a multimode fibre as an imaging tool. Based on this new approach, the scientists designed a compact…
Broadband Light Sources With Liquid Core
The researchers pumped a hybrid waveguide with an ultrafast, intense laser pulse and produced a very broad light spectrum in the near and mid-infrared range (1.1 μm to 2.7 μm) not visible to the human eye. Due to the unique characteristics of the liquid fiber core, the light pulse is broken up into solitons —…
