“…2, inset). This Sb value is comparable to those reported for other single-layer waveguide DFB sensors (Sb = 20 nm/RIU at n = 1.33) [16,24], which have demonstrated their capability to detect biomolecules [16,41]. This indicates that our PDI-O-based DFB sensors have sufficient sensitivity to be used for biomolecule detection.…”

“…A wide variety of materials have been used to fabricate the active layers of DFB sensors: organic semiconductors prepared as neat films, such as truxene-core molecules [24] or semiconducting polymers [25]; or laser dyes dispersed in inert polymers, for example Rhodamine 590 in the SU-8 resist [19,26], Coumarin 503 in poly(methyl methacrylate) (PMMA) [16] or Pyrromethene 597 in Ormocore [21]. Among many families of laser dyes, pyrromethenes and perylenediimides (PDIs) are among the most photostable (independently on the type of matrix or device).…”

“…There has been extensive work in the development of sophisticated matrixes including the dye covalently linked (not dispersed), in which dyes such those of the Rhodamine family, or others, can improve their photostability significantly [27]. [24,31]. Another remarkable property of PDI-doped PS materials is their excellent thermal and chemical stability, which enables grating imprinting by thermal-NIL directly onto the active film and consequently in a very simple and economical way [32].…”

“…Exposure to explosives inhibits lasing by increasing the laser threshold. DFB lasers sensitivity to environmental refractive index variation was also recently demonstrated for both polymer and silica substrates patterned by NIL [190][191][192]. In these devices a gain material is deposited on a grating to achieve lasing.…”

In this chapter we review the use of nanoimprint lithography and its derivative soft-lithography techniques for the fabrication of functional photonic crystals. Nanoimprint is a viable, scalable, and cost-effective solution for large area patterning. While initially it relied primarily on pattern transfer from a rigid mold to a thermally softened polymer by embossing, in the last two decades the process evolved rapidly, giving rise to new technologies that allow direct imprint of functional materials such as conjugated polymers, metals, biological matter, and metal oxides. These advancements generated increasing interest in the use of nanoimprint lithography for the fabrication of photonic structures for light management in optoelectronic devices. After describing standard nanoimprint lithography and its derivative soft-lithography methods, we briefly discuss nanoimprint capabilities and prospects in photonic applications. In particular we review recent implementations of imprinted photonic structures for light management in organic light emitting diodes, solar cells, solid state lasers and sensors.

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 refractive index sensing capabilities, under exposure to liquids of different refractive index, have been determined from changes in their emission wavelength. The role of the active film thickness on both, the laser and the sensing performance, has been explored. The use of a thick active film (850 nm) allows obtaining the lowest possible threshold and highest operational lifetime for this type of device although the sensor sensitivity is lower than that achievable with a thin film (160 nm). It is also shown that the inclusion of a high refractive index TiO 2 layer on top of the sensor structure allows improving the sensor sensitivity by around two times.
