Witryna7 kwi 2024 · Locking to 4-m length fiber resonator causes a drastic narrowing of the DFB laser linewidth down to 2.8 kHz and a reduction of the laser phase noise by three orders of magnitude. WitrynaDFB lasers and DBR lasers share many of the same characteristics of narrow linewidth and tunability. Whereas DBRs have a Bragg reflector separated from the gain region, DFB lasers have a feedback structure consisting of a low-contrast, weakly reflecting Bragg reflector distributed along the entire length of the gain ridge, hence the name ...
