Presentations

Photonic Chip-Based Optical Nanoscopy (STu1A.1)
Presenter: Balpreet Ahluwalia, UiT, The Arctic University of Tromsø

A photonic chip-based approach is shown as alternative to conventional super-resolution fluorescence microscopy. By making use of photonic circuits, more compact, cost-effective and higher resolving setups can allow for a wider implementation of these techniques.

High-Aspect-Ratio Free-Standing Membrane Waveguides for Mid-Infrared Nanophotonics (STu1A.2)
Presenter: Marek Vlk, UiT, Dept of Physics and Technology

Nanophotonic devices for optical sensing often display poor evanescent field interaction. We demonstrate a suspended thin-film waveguide with stronger light–analyte interaction than a free-space beam, as verified by detecting acetylene at 2566 nm.

  Paper

Distributed Temperature Sensing Based on φ-OTDR Using Back-Reflection-Enhanced Fiber (STu1A.3)
Presenter: Malak Galal, Ecole Polytechnique Federale de Lausanne


Distributed temperature sensing with 10 dB back-reflection-enhanced fiber is performed based on φ-OTDR. While the temperature sensitivity of such fibers is similar to that of standard single-mode fibers, a 3-times higher temperature resolution is observed.

  Paper

Integrated Near-Infrared Spectral Sensor Based on Near-Infrared Detector Arrays (STu1A.4)
Presenter: Kaylee Hakkel, Eindhoven University of Technology

We present a spectral sensor based on an integrated array of resonant-cavity-enhanced photodetectors operating in the near-infrared. Prediction models are built directly using the 15 photodetector responses, without the need for spectral reconstruction.

  Paper

Wide-Field Magnetic and Thermal Imaging of Electric Currents Using NV- Centers in Nanodiamond Ensembles (STu1A.5)
Presenter: Siamak Dadras, University of Rochester

Magnetic and thermal microscopy can be performed concurrently to probe physical performance of integrated circuits. We present wide-field imaging of current-induced magnetic and thermal patterns using optically-detected magnetic resonance of NV- centers in nanodiamond ensembles.

  Paper

Photonic Integrated Alumina Waveguide Gratings for far-Field Structured Illumination at UV Wavelengths (STu1A.6)
Presenter: Chupao Lin, Ghent University

We demonstrate far-field UV structured illumination implemented with integrated aluminum oxide (AlOx) waveguide gratings. Based on simulation and experimental results, we discuss the performances of two AlOx waveguide gratings operating at λ= 360nm.

  Paper

Low-Loss Nanoslot Waveguides for Sensing Fabricated in a CMOS Foundry (STu1A.7)
Presenter: Todd Stievater, US Naval Research Laboratory

We demonstrate propagation loss as low as 0.3 dB/cm and high-fidelity sensing in foundry-fabricated silicon nitride nanoslot waveguides designed for wavelengths between 700 nm and 1600 nm.
