Thermal-nanoimprint lithography for perylenediimide-based distributed feedback laser fabrication

Abstract

In the present work thermal nanoimprint lithography of various commercial thermoplastic resists as matrixes for perylenediimides (PDIs) has been studied. This fabrication method reduced the number of fabrication steps, and therefore, the cost of the obtained distributed feedback (DFB) lasers. The optical properties of these devices are analyzed, aiming to optimize their performance. Thermal AbstractIn the present work thermal-nanoimprint lithography of various commercial

Plasmonic Enhancement in the Fluorescence of Organic and Biological Molecules by Photovoltaic Tweezing Assembly

“…PDI‐O is a quite photostable molecule with a very high FL quantum yield (close to 1) when dispersed at concentrations of 1 wt%, or below, in inert thermoplastics polymers such as PMMA and polystyrene. These systems have shown a very good performance as active material in waveguide‐based organic lasers . Moreover, the potential of distributed feedback lasers based on this active system as refractive index or biological sensors has been recently demonstrated.…”

Nanoimprint Lithography: Toward Functional Photonic Crystals

“…Direct imprinting reduces the fabrication process to one single step, thus decreasing material consumption as well as fabrication time and costs. As a result, standard T-and UV-NIL were applied to DFB distributed feedback laser [159], BEL band edge laser [173] dye doped resist to obtain low threshold distributed feedback [168][169][170][171] and band edge lasers [172][173][174][175] (Table 3). PhC can also be directly imprinted into gain polymers and oligomers.…”
