Da sich DBR als Forschungsansatz versteht, ist die Frage nach geeigneten Standards der DBR-Forschung mehr berechtigt. Reinmann (2022) versucht in ihrem Beitrag an Antworten und formuliert Standards, im Erkenntnis- wie auch Gestaltungsanspruch gerecht werden möchten. Die Herangehensweise von eröffnet eine Perspektive jenseits verschiedensten DBR-Modelle erlaubt einen anderen, frischen Blickwinke...

分布式布拉格反射镜（DBR）是共振腔发光二极管（RCLED）的主要组成部分，其温度特性对RCLED的性能有着重要影响。基于650 nm红光RCLED，设计出由Al0.5Ga0.5As和Al0.95Ga0.05As组成的DBR结构。首先通过AlxGa1-xAs材料折射率的色散关系分析温度对AlxGa1-xAs材料折射率的影响，进而模拟了DBR反射谱的温度特性，得到随着温度升高DBR反射谱红移的结论，温漂速率为0.048982 nm/℃。通过MOCVD制备出30对Al0.5Ga0.5As和Al0.95Ga0.05As组成的DBR外延结构，并对其进行反射谱测试，发现随着温度升高反射谱出现了红移现象，温漂速率为0.049277 nm/℃，与模拟结果相近，验证了温度升高导致反射谱红移结论的正确性。

We propose and experimentally demonstrate a planar array of optical bandpass filters composed of low loss dielectric metasurface layers sandwiched between two distributed Bragg reflectors (DBRs). The two DBRs form a Fabry-Pérot resonator whose center wavelength is controlled by the design of the transmissive metasurface layer which functions as a phase shifting element. We demonstrate an array ...

This Letter presents distributed Bragg reflector (DBR) fiber lasers for high-temperature operation at 750°C. Thermally regenerated fiber gratings were used as the feedback elements to construct an erbium-doped DBR fiber laser. The output power of the fiber laser can reach 1 mW at all operating temperatures. The output power fluctuation tested at 750°C was 1.06% over a period of 7 hours. The the...

Apparent personality analysis (APA) is an important problem of personality computing, and furthermore, automatic APA becomes a hot and challenging topic in computer vision and multimedia. In this paper, we propose a deep learning solution to APA from short video sequences. In order to capture rich information from both the visual and audio modality of videos, we tackle these tasks with our Deep...
