Figure 1: The slow optical cooking setup: A silica microfibre filled with deionised water is coupled to two microfibers, MF1 and MF2, which are oriented perpendicular to the microfibre and connected to an optical spectrum analyser and broadband light source. The heating effect caused by the broadband WGMs is illustrated in red.
