Nettet7. mai 2024 · However, with some lines and errorbars in one plot, this gets a bit messy. What I wanted to do, is to highlight the "main marker line" (the "mw" values so to say) to make them stand out a bit more. But if I do it via "LineWidth", the main line plus errorbar becomes bigger. Is there a way to exlude the errorbars? Nettet5. nov. 2024 · Narrow linewidth lasers have many applications, such as higher order coherent communications, optical sensing, and metrology. While semiconductor lasers are typically unsuitable for such applications due to relatively low coherence, recent advances in heterogeneous integration of III-V with silicon have shown that this is no longer true.
