Experimental Evidence for Superprism Effects in Three‐Dimensional Polymer Photonic Crystals

Spectral Redistribution in Spontaneous Emission from Quantum‐Dot‐Infiltrated 3D Woodpile Photonic Crystals for Telecommunications

“…However, experimental study on emission control of QDs with 3D PCs in the near-infrared (NIR) wavelength region, which holds a key to next generation photonic devices for telecommunications, [10][11][12][13] has not yet been demonstrated. By using the twophoton polymerization (2PP) method, [14][15][16][17][18] high quality 3D…”

“…Here, we report, for the first time, on the spectral redistribution in spontaneous emission from PbSe QDs infiltrated in a 3D NIR woodpile PC fabricated by the 2PP method. 2PP is a fast, direct laser writing method and has been used to produce 3D high quality PCs of woodpile [16][17][18] and other structures. [20] By controlling the threshold during the 2PP process, [15,18,21] it is possible to produce 3D woodpile PCs with stop gaps in the NIR range.…”

In this work, the 3D woodpile PC fabricated by using the 2PP method (see Experimental) was formed layer-by-layer, directly on a cover glass, as illustrated in Figure 1a.…”

Optical storage arrays: a perspective for future big data storage

“…In recent decades, nanophotonics has emerged as a rapidly expanding new field of light-matter interaction, largely owing to recent advances in nanotechnology that permit better control of material properties at the nanometer scale as well as the availability of sophisticated nanophotonic probes. As such, studies based on the new photonic principles have led to the development of artificial materials with negative refractive indices, [10][11][12] nano-optical circuits, 13,14 nanoscale light-emitting sources, 15,16 imaging beyond the diffraction limit [17][18][19] and superresolution optical lithography. 20,21 These studies have laid the physical groundwork for the confinement of light-matter interactions to the nanometer scale, which paves the way toward breaking or circumventing the diffraction barrier and thus increasing storage capacity by using entirely new nanophotonic approaches.…”

Evidence of near-infrared partial photonic bandgap in polymeric rod-connected diamond structures

“…In recent years, much effort has been devoted to the fabrication of 3D PhCs in the near-infrared communication band (1.3-1.7 µm) [2][3][4][5][6][7][8][9] and the visible wavelength range [10]. Among these, fabrication of 3D structures by direct laser writing (DLW) using two-photon polymerization (TPP) [11] has been studied extensively due to its great flexibility and its capability to precisely recreate complex geometries.…”
