Thermal Shrinkage‐Induced Modifications in Photonic Bandgaps of Two‐Photon Polymerized Bragg Reflectors

open access: yesAdvanced Photonics Research, EarlyView.
Scanning electron microscopy and white‐light reflectance images of the pillar‐supported distributed Bragg reflector (DBR) are presented before and after thermal shrinkage. The DBR, fabricated via two‐photon polymerization, consists of alternating high‐ and low‐index layers supported by vertical pillars.

Effects of Extreme Mirror Downscaling on Open Micro‐Fabry–Perot Spectral Responses and Resonant Mode Profiles

open access: yesAdvanced Photonics Research, EarlyView.
Extreme miniaturization of Fabry–Perot cavities has severe impacts on their spectral response and spatial distribution of the resonant modes. A fully analytical methodology is proposed accounting for the finite borders of the micromirrors to predict this behavior. Model validation relies on comparing with measurements obtained on silicon micro‐cavities

Experimental Test of the Three‐Setting Clauser–Horne–Shimony–Holt Inequality with Nonmaximally Orbital Angular Momentum Entangled States

open access: yesAdvanced Photonics Research, EarlyView.
Herein, the maximum violation of the three‐setting Clauser–Horne–Shimony–Holt (CHSH) inequality using nonmaximally entangled photons with orbital angular momentum is demonstrated. By mapping the optimization problem to maximizing a triangle's perimeter inscribed in an ellipse, the experiment validates the geometric approach and highlights the ...

All‐Dielectric Metasurface‐Based Gap Waveguides

open access: yesAdvanced Photonics Research, EarlyView.
Dielectric metasurface‐based waveguides (metawavegides) offer several advantages over conventional waveguides, making them ideal for integrated photonics. A design of a metawaveguide composed of a pair of dielectric metasurfaces is proposed, where each metasurface behaves as a wall of either a perfect electric conductor or a perfect magnetic conductor,
