From: Electrically controlled white laser emission through liquid crystal/polymer multiphases
a Photograph of an oWL device whose emission intensity is controlled by an external applied voltage. b oWL emission intensity vs. applied DC voltage. The device is pumped at an excitation fluence of 11.9 mJ/cm2. Inset: lasing intensity for consecutive voltage cycles of 0–5 V applied to the device
