“…However, laser systems that emit white light and are based on organic active materials have only been reported in a very few pioneering works [26][27][28][29] . Such organic white lasers (oWLs) are mostly achieved by combining the output beams of individual lasers, each emitting at a single (blue, green, and red) colour.…”

White lasers are becoming increasingly relevant in various fields since they exhibit unprecedented properties in terms of beam brightness and intensity modulation. Here we introduce a white laser based on a polymer matrix encompassing liquid crystals and multiple organic chromophores in a multifunctional phase-separation system. The separation of the hydrophilic matrix and the hydrophobic liquid crystals leads to the formation of a complex optically active layer, featuring lasing emission tuneable from blue to red. White laser emission is found with an optical excitation threshold of approximately 12 mJ/cm 2. Importantly, an external electric field can be used to control the device emission intensity. White lasers with low-voltage (≤10 V) controllable emission might pave the way for a new generation of broadband light sources for analytical, computational, and communication applications.

“…Generally, the threshold, as one of the most important parameters of the polymer lasers, is decided by the balance between the gain and loss. Specifically, the threshold was controlled by the main parameters of the cavity, such as the material [19][20][21][22][23], the type [24][25][26], the quality [27,28], and the size [29][30][31]. Recently, the dependence of the laser threshold on the pump spot diameter was studied in the DFB cavity [29,30].…”

Pump Polarization and Size Effects on the Performance of Polymer Lasers

et al. 2019

The parameters of a pump have a marked influence on the performance of distributed feedback polymer lasers. Our polymer laser consisted of a grating and a polymer film. We fabricated the grating using interference lithography. The polymer film was spin coated on the grating. A half-wave plate was used to change the pump polarization, and an x-y slit was used to change the pump size. The direction of grating lines were parallel to the x axis of the slit. The laser performance was modified by changing the polarizations and sizes of the pump beam. The lasing threshold increased more rapidly with decreasing pump size in the y direction than in the x direction. The influence of the pump polarization on the lasing threshold for decreasing pump size in the x direction was greater than that for decreasing pump size in the y direction. These results may be useful for the miniaturization of distributed feedback polymer lasers.

“…These properties enable the construction of a variety of different types of sensors on flexible glass that require high processing temperature or harsh chemicals during manufacturing, while these devices cannot be constructed on flexible plastics. There have been a few studies about the construction of devices based on flexible glass, such as solar cells , , , and lasers , . However, to the best of knowledge, there is no report until now for the construction of an amperometric sensor based on flexible glass.…”

The development of flexible sensors could enable significant advances in clinical diagnosis, defense, and environmental monitoring. Flexible glass provides the flexibility and possesses stable chemical and physical properties. Here, we show that carbon graphite and silver/silver chloride inks can be printed onto flexible glass to construct amperometric sensors, and the sensors show sensitive and rapid detections of hydrogen peroxide. We anticipate that these results could provide exciting avenues for fundamental studies of flexible electronics and flexible bioelectronics, as well as a variety of applications in fields ranging from medical diagnosis to defense.
