Label-free sensors based on perylenediimide-doped polystyrene distributed feedback lasers
Distributed feedback (DFB) laser sensors with active films consisting of a highly efficient and photostable perylenediimide dye (perylene orange, PDI-O) dispersed in polysytrene (PS), used as passive matrix, are reported. PDIdoped-PS DFB lasers show an excellent operational durability under ambient conditions, superior to those of previously reported DFBs used for sensing purposes. Their bulk r...
متن کاملUltrasensitive Magnetic Field Sensing Based on Refractive-Index-Matched Coupling
An ultrasensitive magnetic field sensor is proposed and investigated experimentally. The no-core fiber is fusion-spliced between two pieces of single-mode fibers and then immersed in magnetic fluid with an appropriate value of refractive index. Under the refractive-index-matched coupling condition, the guided mode becomes leaky and a coupling wavelength dip in the transmission spectrum of the s...
متن کاملDistributed Feedback Lasers Based on Thiophene/Phenylene CoOligomer Single Crystals
Organic solid state lasers have attracted considerable attentions because they have the potential to be tunable, flexible, biocompatible, and easily integrated into plastic optoelectronics.[1–8] Optically pumped laser has been reported in a very broad range of conjugated polymers and oligomers. However, for the electrically pumped organic lasers, there still exist many challenging problems to b...

متن کاملAll-optical on-chip sensor for high refractive index sensing
A highly sensitive sensor design based on two-dimensional photonic crystal cavity is demonstrated. The geometric structure of the cavity is modified to gain a high quality factor, which enables a sensitive refractive index sensing. A group of slots with optimized parameters is created in the cavity. The existence of the slots enhances the light–matter interactions between confined photons and a...
