DOI: 10.1063/1.5080266

Abstract: We report on the fabrication of high-power, high-spectral-purity GaSb-based laterally coupled distributed feedback (LC-DFB) lasers emitting at 2 μm. Second-order Chromium-Bragg-gratings are fabricated alongside the ridge waveguide by lift off. Due to the introduction of gain… read more here.

DOI: 10.1093/aob/mcac069

Abstract: Abstract Background The colours of flowers are of key interest to plant and pollination biologists. An increasing number of studies have investigated the importance of saturation of flower colours (often called ‘spectral purity’ or ‘chroma’)… read more here.

DOI: 10.1364/oe.567657

Abstract: This study analyzes the spectral purity of microwaves generated using two mutually injected semiconductor lasers with highly different injection powers. While the strong optical injection from the first laser excites the period-one dynamics in the… read more here.

DOI: 10.1364/ol.463950

Abstract: Random distributed feedback (RDFB) cascaded Raman fiber lasers (CRFLs) are simple, wavelength agile, and enable high-power fiber lasers outside emission bandwidths of rare-earth doped fiber lasers. However, the spectral purity, defined as the percentage of… read more here.
