“…Light was injected into the waveguide and propagated to the disk were light remains confined at the edges of the disk. The strong bend implies a large evanescent field in the surrounding medium, which can be exploited for evanescent coupling towards sub-micronic or micronic structures [26] or for species detection [16]. …”

Abstract:We report on optical components for integrated optics applications at the micro-and nanoscale. Versatile shapes and dimensions are achievable due to the liquid phase processability of SU8 resist. On the one hand, by adjusting the UV-lithography process, waveguiding structures are patterned and released from their original substrate. They can be replaced on any other substrate and also immerged in liquid wherein they still show off efficient light confinement. On the other hand, filled and hollow 1D-nanostructures are achievable by the wetting template method. By exploiting the large range of available SU8 viscosities, nanowires of diameter ranging between 50 nm and 240 nm, as well as nanotubes of controllable wall thickness are presented. Optical injection, propagation, and coupling in such nanostructures are relevant for highly integrated devices.

“…Steinhart and co‐workers investigated in detail the mechanisms involved in wetting‐template methods, showing that capillarity forces, solidification mechanisms (upon temperature or evaporation of the solvent), and polymer–pore surface interactions control the formation of nanowires or nanotubes . Figure B shows the schematic procedures of the synthesis of nanowires and nanotubes by the wetting‐template method . This solvent‐assisted template method can produce nanowires or nanotubes in hard templates depending on the kind of membrane used and on the volume and concentration of the deposition solution.…”

to their wide range of tunable and potentially enhanced properties, as well as solution processing. Among the numerous conducting and semiconducting conjugated polymers processed into NWs and NTs and mentioned in this report, one can point out polythiophene (PT) and its derivatives, such as poly(3-metylthiophene) (P3MT), poly(3-butylthiophene) (P3BT), poly(3-hexylthiophene) (P3HT) andpoly(3,4-ethylene-dioxythiophene) (PEDOT), polypyrrole (PPy), polyaniline (PANi), polyphenylene-vinylene (PPV) andpoly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene](MEH-PPV), poly(9,9-dioctylfl uorene) (PFO), poly(9,9dioctylfluoreneco -benzothiadiazole) (F8BT), etc. Additionally, polymer nanocomposites, i.e. functional nanoparticles (NPs) inserted into a conjugated or notconjugated polymer matrix, are an exciting alternative to benefi t from the intrinsic properties of NPs and from the processability of polymers for 1D nanostructuring. Polymer nanocomposites have been processed into nanofi bers, for example by electrospinning and templating methods. Ultimately, optimal design with the juxtaposition of two or more materials in a 1D-like nanostructure is expected to promote improved properties, new behaviors, or to meet technological challenges. This is an emerging domain with very exciting perspectives.Although nanowires and nanotubes are the most common 1D-like morphologies, many others have been achieved with polymers, including nanofi bers, nanoribbons, nanorods, and nanosprings. The assembly and manipulation of such 1D building-blocks are still quite challenging due to their relative mechanical weakness because of their small diameter and very large aspect ratio. While in-solution methods are well developed for the assembly of nanostructures, the chemical stability of polymers in many commonly used liquids can also be a restraining factor.In the fi rst part of this review, the principles and recent developments of the main strategies used to synthesize polymeric 1D nanostructures are exposed. An emphasis is made on hardtemplating and electrospinning methods because structures with very high aspect ratios can be achieved, as are required for many photonic applications. In the second part, the various optical, optoelectronic, and photonic properties measured for these one-dimensional nanostructures are reviewed, including There is tremendous interest in one-dimensional nanostructures, since they permit enhanced properties as well as new paradigms for electronic, optical, optoelectronic, and photonic devices. Besides inorganic systems, nanowires (NWs) and nanotubes (NTs) containing an optically active polymer are now being intensively investigated. This article reviews recent developments in the various preparation methods and in the optically related properties of polymer-based NWs and NTs. The case of both conjugated polymers (CPs) and polymers containing photo-active species is described herein. The latest developments in synthesis methods allow the design of NWs and NTs with improved features or with more complex architect...

“…1 However, these approaches require micronic coupling distances and do not allow to fully optimise the quality of the injection in nanostructures nanoscale. In previous publications, 5,6 we have reported the single-mode behavior hybrid mode HE 11 of SU8 polymer nanowires and nanotubes by theoretical and experimental approach.

We report photonic concepts related to injection and sub-wavelength propagation in nanofibers (nanowires and nanotubes). These nanostructures are fabricated by the wetting template method leading to aspect ratio of over 250. At first, injection into nanowires and nanotubes of SU8, a photoresist used for integrated photonics, was successfully achieved by using polymer microlensed fibers with sub-micronic radius of curvature. Theoretical simulation by finite domain time-dependent (FDTD) method was used to determine the sub-wavelength propagation for nanowires and nanotubes and corroborate this coupling phenomena. The original confinment of energy density into SU8 nanotubes is highlighted. Finally, characterisation of propagation losses is reported by using a cut-back method transposed to such nanotubes and determined to range between 1 and 2 dB/mm. Both injection and cut-back method developed here are compatible with any sub-micronic structures. This work on SU8 nanofibers suggests broader perspectives for future nanophotonics.
