Metal organic framework (MOF) microcrystals for multicolor broadband lasing

Multicolor single-mode polarized microlasers containing an output range from visible light to the near-infrared have significant applications in photonic integration and multimodal chemical sensing or imaging applications. However, such devices are very difficult to realize in practice. In a new report, Huajun He and a research team in physics, materials science and chemistry in Singapore, China and the U.S., developed a single crystal with multiple segments to generate controlled, single-mode, ...
