Abstract The technology of RGBY micro resonant cavity light emitting diodes (micro-RCLEDs) based on quantum dots (QDs) is considered one of the most promising approaches for full-color displays. In this work, we propose a novel structure combining a

The metal-dielectric dimer is an ideal structure for enhancing single-molecule fluorescence. When a single-molecule interacts with the metal-dielectric dimer, the metal-dielectric plasmonic system creates strong resonance, which amplifies the electri

The 3D-printing of dielectric superstrates of Resonant Cavity Antennas has advantages of fast prototyping and flexibility in the realization of customized layouts. In this work, the low dielectric permittivity of test filaments is experimentally meas

Open resonant cavity antenna (ORCA) and its recent advances promise attractive features and possible applications, although the designs reported so far are solely based on the classical electromagnetic (EM) theory and general perception of EM circuit

Resonant cavity antennas (RCAs) produce reasonably high gains (15-20 dBi) with thin form factors, and find strong applications in wireless communication. A recently proposed RCA achieves a broad 3dB bandwidth of over ${20\%}$ using a spherically modi

We experimentally demonstrate a scheme for generating massively parallel and real-time physical random bits (PRBs) by using weak-resonant-cavity Fabry-Perot laser diodes (WRC-FPLDs) with optical feedback. By using external optical feedback to modify

The counterfeiting of integrated circuits (ICs) has been a growing issue. Current available methods used to detect counterfeit ICs can be expensive, imprecise, and time-consuming. This paper explores the resonant cavity system: a non-contact, non-des

We demonstrate substrate-emitting resonant cavity interband cascade light emitting diodes (RCICLEDs) based on a single distributed Bragg reflector (DBR). These devices operate in continuous wave mode at room temperature. Compared to standard ICLEDs w
