Organic Semiconductor Laser

All-polymer organic semiconductor laser chips: parallel fabrication and encapsulation.

Organic semiconductor lasers are of particular interest as tunable visible laser light sources. For bringing those to market encapsulation is needed to ensure practicable lifetimes. Additionally, fabrication technologies suitable for mass production must be used. We introduce all-polymer chips comprising encapsulated distributed feedback organic semiconductor lasers. Several chips are fabricate...

Nanoimprinted organic semiconductor laser pumped by a light-emitting diode.

An organic semiconductor laser, simply fabricated by UV-nanoimprint lithography (UV-NIL), that is pumped with a pulsed InGaN LED is demonstrated. Molecular weight optimization of the polymer gain medium on a nanoimprinted polymer distributed feedback resonator enables the lowest reported UV-NIL laser threshold density of 770 W cm(-2) , establishing the potential for scalable organic laser fabri...

Temperature-Insensitive Semiconductor Laser

The Semiconductor Laser

Chaos is a fundamental property that possesses nonlinearity and a sensitive dependence on initial conditions. Because of the nonlinearity in a chaotic system it becomes very difficult to make accurate predictions about the system over a given time interval. Weather forecasting is an example of how chaos theory effects the accuracy of predictions over a given time interval. Through analyzing a w...

High mobility emissive organic semiconductor

The integration of high charge carrier mobility and high luminescence in an organic semiconductor is challenging. However, there is need of such materials for organic light-emitting transistors and organic electrically pumped lasers. Here we show a novel organic semiconductor, 2,6-diphenylanthracene (DPA), which exhibits not only high emission with single crystal absolute florescence quantum yi...
