“…Master gratings were defi ned using a Leo 1530/Raith Elphy Plus system in an electron-beam resist (ZEON ZEP 520A), which was spin-coated on top of a silicon wafer. The electronbeam resist was developed using xylene at 23 ° C and the pattern (1 mm × 1 mm total area) was transferred into the silicon master using reactive ion etching (RIE) with a combination of SF 6 and CHF 3 gas (at a 1:1 ratio). The resulting master structures were transferred onto a silica substrate using UV-nanoimprint lithography by creating a perfl uoropolyether daughter stamp from the master structure and then using that as a mold for replicating the structures onto a photoresist (Micro Resist Technology UVCur06), spin-coated on top of a glass substrate that had been pretreated with an adhesion promoting agent (Micro Resist Technology mr-ASP1).…”

“…Organic nonlinear optical (NLO) materials are continuing to receive great interests due to their wide applications in laser technology , optical data storage and terahertz (THz) wave generation , etc . In the past decades, extensive efforts have been made to construct noncentrosymmetric (NCS) arrangement of molecules, which is indispensable for second‐order nonlinear optical crystals .…”

A new quadratic nonlinear optical crystal, 2‐amino‐3‐nitropyridinium trichloroacetate (2A3NPTCA), was synthesized and the single crystals were grown by slow evaporation method at room temperature. Single crystal X‐ray diffraction and powder X‐ray diffraction experiments were carried out in order to confirm the structure and crystalline nature of 2A3NPTCA crystal. The chemical bonding and various functional groups present in the 2A3NPTCA were identified from FT‐IR spectrum. The UV–visible–NIR transmission spectrum shows that it is suitable for frequency‐converting in the wavelength region of 431–1200 nm. Thermogravimetric (TG) and differential thermal analysis (DTA) were carried out to characterize the thermal behaviors of the grown crystals. Kurtz and Perry powder method for second harmonic generation (SHG) measurements demonstrate that 2A3NPTCA is a phase matching material and its nonlinear optical efficiency is two times that of KDP. All the above results suggest that 2A3NPTCA is a potential candidate of NLO material.

“…While a sub-micron PVA film might not totally suppress photo-oxidation of OS, it is still expected to slow down the process. The device was then annealed in air for three days at 35°C in order to totally evaporate the solvent and obtain a good crystalline cohesion [10].…”

“…They also benefit from potential low production cost and toxicity while their 'soft matter' nature offers great processing flexibility, enabling for example a wide range of novel bendable and mechanically-tunable devices such as OS lasers [2][3][4][5][6][7][8]. Wavelength electrical-tuning of OS lasers has also been shown [9][10][11]. Consequently, research on easy-to-fabricate and potentially disposable OS lasers based on these materials is being keenly pursued [12].…”

These lasers are compatible with mechanically-flexible platforms and were entirely fabricated using softlithography and spin-coating techniques. The gain elements in both types of lasers were monodisperse -conjugated star-shaped macromolecules (oligofluorene truxene, T3). In the nanocomposites lasers, these elements were incorporated into a transparent polyimide matrix, while in the encapsulated devices a neat layer of T3 was overcoated with Poly(vinyl alcohol) (PVA). The T3-nanocomposite devices demonstrated a 1/e degradation energy dosage up to ~27.0 ± 6.5 J/cm 2 with a threshold fluence of 115 ± 10 µJ/cm 2 . This represents a 3-fold improvement in operation lifetime under ambient conditions compared to the equivalent laser made with neat organic films, albeit with a 1.6-time increase in threshold. The PVA-encapsulated lasers showed the best overall performance: a 40-time improvement in the operation lifetime and crucially no-trade-off on the threshold, with respectively a degradation energy dosage of ~280 ± 20 J/cm 2 and a threshold fluence of 36 ± 8 µJ/cm 2 .© 2013 Optical Society of America , 1985). 17.
