High‐Resolution On‐Chip Digitally Tunable Spectrometer Based on Double‐Cascaded Ring Resonators

open access: yesAdvanced Photonics Research, EarlyView.
An integrated spectrometer is here presented, based on two cascaded ring resonators covered with a phase change material. The Vernier architecture is implemented allowing for a digital scan of wavelengths. Resolution smaller than 0.1 nm can be achieved, together with a footprint ≈0.03 mm2 and a bandwidth of the order of tens of nanometers.

Formation Control of Multi‐Agent System with Local Interaction and Artificial Potential Field

open access: yesAdvanced Robotics Research, EarlyView.
This article proposes a local interaction‐based formation control method for Multi‐Agent system, integrating consensus and leader‐follower strategies with a stress response mechanism—artificial potential field to reduce communication overhead and enable obstacle avoidance. Experimental results on triangular, square, and hexagonal formations confirm its
