“…5d-f). The thresholds obtained are comparable to those previously reported on similar blue, 17,40 green-yellow, 41,42 and red 43,44 DFBs on nanostructured rigid substrates as well as on nanostructured photoresists. 45,46 The slopes of the input-output curves for F8BT and F8BT:P3HT are 5.5 and 50 times lower, respectively, than the corresponding slope for PFO, which suggests superior optical gain properties in PFO.…”

Here we present the assembly of novel transparent all-polymer distributed feedback (DFB) lasers. Flexible and highly transparent cellulose diacetate (CdA) was employed as substrate on which gratings with different periods were engraved by thermal nanoimprinting with high fidelity. Highly luminescent conjugated polymers (CP), poly (9,9-dioctylfluorene) (PFO), poly(9,9dioctylfluorene-alt-benzothiadiazole) (F8BT), and a blend of F8BT and poly(3-hexylthiophene)-poly(9,9-dioctylfluorene-altbenzothiadiazole) (P3HT:F8BT) were deposited by spin coating onto the nanostructured plastic surfaces, giving rise to perpendicular single-mode lasing emission in the blue, green, and red wavelength ranges, respectively. These lasers show linewidths below 1 nm and low thresholds (≈6 μJcm −2 for blue and red lasing emission), comparable to other state-of-the-art lasers obtained from similar optical gain materials on rigid substrates. The followed strategy is scalable and versatile, enabling the development of large area nanoimprinted DFB lasers (>1cm 2 ) on plastic, which is highly relevant for applications in various markets.npj Flexible Electronics (2019) 3:17 ; https://doi.

“…29,30 As such, holograms offer great potential to function as devices for broad applications such as colored 3D image storage, 22,23,31 glass-free 3D dynamic display, 32,33 graded rainbow patterning, 17,34 and optically responsive sensing. 35 Among all holograms, holographic polymer dispersed liquid crystals (H-PDLCs), pioneered by Sutherland and coworkers in 1993, 36,37 have drawn extensive research interest because of their fantastic switchable electro-optical properties and their great application potentials in biomedical tunablefilters, 38 organic distributed feedback lasers, 39,40 optically switchable photonic structures, 41 displays, 42,43 and so forth. H-PDLCs are typically formed via photopolymerization induced phase separation, i.e., photopolymerization takes place in the bright regions of the interference patterns, resulting in a chemical potential difference between the bright and dark regions.…”

“…In the past two decades, organic solid-state lasers (OSSLs) 1 2 3 4 5 6 7 8 9 10 11 12 13 have been developed extensively because of the easy fabrication of laser devices by spin-coating or solution casting, the low cost of device fabrication, and the wide variation of the lasing wavelength, ranging from the visible to near infrared regions, that can be selected depending on the laser dye used. Slope efficiency is an important measure to evaluate the performance of the laser devices.…”

Organic solid-state lasers (OSSLs) with distributed feedback structures can detect nanoscale materials and therefore offer an attractive sensing platform for biological and medical applications. Here we investigate the lasing characteristics, i.e., the threshold and slope efficiency, as a function of the grating depth in OSSL devices with distributed feedback (DFB) structure fabricated using photoresists. Two types of photoresists were used for the DFB structures: a negative photoresist, SU-8 2002, and a positive photoresist, ma-P 1275. The DFB structure was fabricated using a Lloyd-mirror configuration. The active layer was a rhodamine 6G-doped cellulose acetate waveguide. The threshold for the first order mode (m = 1) was lower than that for the second and third order modes (m = 2, and 3). A low threshold of 27 μJ cm−2 pulse−1 (58 nJ) was obtained using SU-8 2002, with m = 1. The slope efficiency was evaluated as a function of grating depth for each mode and increased as the grating depth increased.
