Self-injection locking to a high-quality-factor microresonator is key component of various up-to-date photonic applications, including compact narrow-linewidth lasers and microcomb sources. For optimal construction such devices it necessary know the parameters mode, which challenging task. We developed verified experimentally an original technique based on fundamentals self-injection effect, allows determining mode (quality factor, vertical index) as well laser diode parameters. demonstrated...
Self-injection locking of a diode laser to high-quality-factor microresonator is widely used for frequency stabilization and linewidth narrowing. We constructed several microresonator-based sources with measured instantaneous linewidths 1 Hz them investigation implementation the self-injection effect. studied analytically experimentally dependence coefficient on tunable parameters such as phase coupling rate.

The advantages of high-quality-factor (high-Q) whispering gallery mode (WGM) microresonators can be applied to develop novel photonic devices for the mid-infrared (mid-IR) range. ZBLAN (glass based on heavy metal fluorides) is one most promising materials used this purpose due low optical losses in mid-IR. We developed an original, best our knowledge, fabrication method melting commercially available ZBLAN-based fiber produce high-Q microspheres with diameters 250 350 μm. effectively excited...
