The tunable thin film organic laser consists of a broadband dielectric stack reflector (shown here in grey), coated with a thin layer of Rhodamine-B doped poly-methyl-methacrylate (shown here in red) and then laminated with a photonic bandgap composite film. Compressing the device changes its emission spectrum. (Credit: Clemson University, US) |
