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...
متن کاملDiode-pumped, mechanically-flexible polymer DFB laser encapsulated by glass membranes.
A diode-pumped, mechanically-flexible organic distributed-feedback laser that is fully encapsulated with ultra-thin glass is reported. The organic laser is excited by 450 nm laser diode and emits at 537 nm with an oscillation threshold of 290 W/cm². The encapsulation format of the device results in a photostability that is improved by two orders of magnitude compared to a non-encapsulated refer...
متن کاملContinuously tunable solution-processed organic semiconductor DFB lasers pumped by laser diode.
The fabrication and characterization of continuously tunable, solution-processed distributed feedback (DFB) lasers in the visible regime is reported. Continuous thin film thickness gradients were achieved by means of horizontal dipping of several conjugated polymer and blended small molecule solutions on cm-scale surface gratings of different periods. We report optically pumped continuously tun...
متن کاملOrganic semiconductor lasers with two-dimensional distributed feedback
Photograph of a mechanically flexible 2D-DFB laser made from the conjugated polymer MeLPPP. The laser is optically pumped well above the threshold for amplified spontaneous emission. The complex far-field emission pattern (blue-green) results from a large detuning between the resonance wavelength and the gain maximum. • A nearly diffraction limited surface emitting conjugated polymer laser util...
متن کاملDC lifetime of encapsulated organic light emitting diodes
Organic light emitting diodes (OLEDs) are ideal sources for chemical and biological optical sensors [1], due to their simplicity, low cost (disposable applications) and possibility to be integrated on chip and fabricated in the form of large 2D arrays (microarray fluorescence [2]) even on flexible plastic substrates. OLEDs with lifetimes of a few hundreds of hours at initial luminance values in...
