On-chip integration of single solid-state quantum emitters with a SiO2 photonic platform

One important building block for future integrated nanophotonic devices is the scalable on-chip interfacing of single photon emitters and quantum memories with single optical modes.*

In the article “On-chip integration of single solid-state quantum emitters with a SiO2 photonic platform” Florian Böhm, Niko Nikolay, Christoph Pyrlik, Jan Schlegel, Andreas Thies, Andreas Wicht,Günther Tränkle and Oliver Benson present the deterministic integration of a single solid-state qubit, the nitrogen-vacancy (NV) center, with a photonic platform consisting exclusively of SiO2grown thermally on a Si substrate.*
The platform stands out by its ultra-low fluorescence and the ability to produce various passive structures such as high-Q micro resonators and mode-size converters. By numerical analysis an optimal structure for the efficient coupling of a dipole emitter to the guided mode could be determined. Experimentally, the integration of a preselected NV emitter was performed with an atomic force microscope and the on-chip excitation of the quantum emitter as well as the coupling of single photons to the guided mode of the integrated structure could be demonstrated. The authors approach shows the potential of this platform as a robust nanoscale interface of on-chip photonic structures with solid-state qubits.*

After optically verifying the successful placement of the nanodiamond hosting a single nitrogen-vacancy ( NV ) center by performing a confocal scan, the article describes how the nanoparticle is pushed to the inner edge of the rib waveguide in a subsequent step, using a NANOSENSORS™ AdvancedTEC™ ATEC-NC tip-view AFM probe.*

Also the deterministic positioning process of the diamond-nanocrystal containing a single NV center (the NV crystal structure is shown in the inset) into the inner edge of the integrated SiO2rib waveguide with an atomic force microscope (AFM) tip, is shown.

Visualizing the bidirectional optical transfer function for near-field enhancement in waveguide coupled plasmonic transducers

In their article “Visualizing the bidirectional optical transfer function for near-field enhancement in waveguide coupled plasmonic transducers” Lauren M. Otto, D. Frank Ogletree, Shaul Aloni, Matteo Staffaroni, Barry C. Stipe and Aeron T. Hammack describe how visualizations of the near-field modes in the region of a plasmonic device were created using scattering scanning near-field optical microscopy and scanning electron microscopy cathodoluminescence with both showing a strong correspondence to multiphysical numerical modeling of the devices under interrogation.

The sSNOM measurements shown in this article were performed with NANOSENSORS™ AdvancedTEC™ ATEC-NC tip-view AFM probes.

Scattering scanning near-field optical microscopy images of HAMR heads as a function of wavelength and polarization. Near-field maps for the 1ω0 and 6ω0 with both (a) 830 nm and (b) 633 nm wavelengths as well as polarizations ranging from −90° deg (perp, TE) to 0° (para TM) to +90° (perp, TE). All maps are 400 nm × 400 nm. The intensity maxima from all maps were extracted and plotted against the expected cos2(θ) intensity decay curve for both (c) 830 nm light and (d) 633 nm light. The full data set ranged from −100° to 100° in increments of 10° and covered six harmonics for both wavelengths. The AFM color scale ranges from −3.8 to +1.6 nm, and the map is 400 nm × 400 nm. Additional images can be found in the Supporting Information in the online version of the original article.
