Directional Whispering Gallery Mode in Microring Lasers Enabled by Tilted Azimuthal Gratings

open access: yesAdvanced Photonics Research, EarlyView.
The chiral light propagation in microring lasers with active cladding, enabled by tilted azimuthal gratings, is illustrated. The symmetry of the whispering gallery mode is disrupted due to scattering losses that are determined by the tilted angle, resulting in distinct clockwise and counterclockwise light propagation, and enabling controlled chirality ...

Improving Light Outcoupling and Addressing Measurement Specifics in Perovskite Light‐Emitting Diodes with Light Management Foils

open access: yesAdvanced Photonics Research, EarlyView.
The necessity and feasibility of enhancing light outcoupling in perovskite light‐emitting diodes (PeLEDs) is highlighted. On near‐IR PeLEDs, low‐cost, micro‐textured light management (LM) foils demonstrate boost in light extraction. Optimizing perovskite thickness and the optical cavity in synergy with LM foils is crucial for maximizing performance ...

Design of Waveguide NbN‐Based Superconductor–Insulator–Superconductor Mixer for 650 GHz

open access: yesAdvanced Photonics Research, EarlyView.
This research work focuses on a waveguide NbN‐based superconductor–insulator–superconductor mixer operating at 650 GHz. The signal coupling circuit is designed using a waveguide‐microstrip coupling structure, and the return loss obtained is lower than −16 dB. For the mixing circuit, its return loss is less than −7.5 dB, and the return loss reduces with
