“…2(b). The physics behind is not difficult since a rather similar phenomenon is already demonstrated via the surface plasmon resonance (SPR), where only one hollow cone of directionally scattered light can be observed33. The experimental difference between the UOMs and the SPR can be easily understood since there is only one resonance dip in the SPR reflection spectrum.…”

Due to the field enhancement effect of the hollow-core metal-cladded optical waveguide chip, massive nanoparticles in a solvent are effectively trapped via exciting ultrahigh order modes. A concentric ring structure of the trapped nanoparticles is obtained since the excited modes are omnidirectional at small incident angle. During the process of solvent evaporation, the nanoparticles remain well trapped since the excitation condition of the optical modes is still valid, and a concentric circular grating consisting of deposited nanoparticles can be produced by this approach. Experiments via scanning electron microscopy, atomic force microscopy and diffraction of a probe laser confirmed the above hypothesis. This technique provides an alternative strategy to enable effective trapping of dielectric particles with low-intensity nonfocused illumination, and a better understanding of the correlation between the guided modes in an optical waveguide and the nanoparticles in a solvent.

International audienceThis study demonstrates the feasibility of enhancing an organic-based plasmon-emitting diode on the directional light beaming efficiency by near-field surface plasmon polaritons (SPPs) in both metal grating and polymer grating nanostructures. The interaction between organic/metal and PR/metal interfaces to cause SPPs can facilitate specific directional emission. Directional emission properties give rise to a spectral band-gap response enhancement. Our results also verify that efficient surface plasmon grating coupled emissions (SPGCEs) can improve directionality under index-mediated tuning. Experimental results indicate SP decoupling emission in the visible light. The subsequent emission intensity can increase by up to 3.5 times. Moreover, a narrow FWHM of approximately 60 nm in a defined direction is achieved, and an SP coupling rate is approximately 80% on the metal grating structure. The proposed method is highly promising for use as an active plasmonic emitter and discoloration biosensors with enhanced SPPs resonance energy, owing to interactions with the organic/metal nanostructur

We present a one-step replication technique for optical gratings that allows the control of the corrugation height and period. By using an ink that slowly condenses into a multilayer polymer, it is possible to control the corrugation height by changing the condensation time. In addition, by applying a mechanical strain on the stamp, it is also possible to change the period of the grating. The combination of these two features added to the ease of use and low cost of this technique makes it very attractive for the fast prototyping of optical gratings for applications such as the measurement of surface plasmon band gaps. Corrugation heights in the range of 100 to 250 nm and period variations up to 10% are achieved.
