Lack of precision and control often produced photonic crystals that have inconsistent defects that jeopardise their commercial performance. Working under a project funded by the EU Future and Emerging Technologies (FET) programme, an international team of researchers (France, Sweden, Israel) has developed a new microfluidic set-up, where researchers can ‘bend matter’, enabling them to re-organise the colloidal droplet clusters used to fabricate the crystals into Tetris-like blocks. The clusters have sizes ranging between two to five monodispersed droplets with an average size of 400nm and are highly replicable. Using this technique allows researchers to easily construct photonic crystals from scratch depending on the application they are eyeing up… read more.
