“…More recently DKS generation and combs have been demonstrated using a variety of compact semiconductor-based sources. In particular, coupling of a high-quality-factor (high-Q) microresonator to a diode laser has been demonstrated to provide laser stabilization and linewidth reduction via the selfinjection locking effect [9][10][11][12][13][14]. Usually, narrow-linewidth laser sources have been used for microresonator pumping and frequency comb generation.…”

We introduce the first principle model describing frequency comb generation in a WGM microresonator with the backscattering-induced coupling between the counter-propagating waves. Elaborated model provides deep insight and accurate description of the complex dynamics of nonlinear processes in such systems. We analyse the backscattering impact on the splitting and reshaping of the nonlinear resonances, demonstrate backscattering-induced modulational instability in the normal dispersion regime and subsequent frequency comb generation. We present and discuss novel features of the soliton comb dynamics induced by the backward wave.

“…2a). Like a standard external cavity diode laser, a self-injection locked WGM laser significantly reduces the linewidth of the laser diode, becoming much narrower than the linewidth of the cavity resonator mode 1,2,[4][5][6][7][8][9][10][11] .…”

“…The simultaneous high power and low linewidth visible wavelength laser was achieved by rarefying the available optical modes of the WGM cavity and controlling the amount of optical feedback to the laser diode. The type of laser presented here should have wide applicability for laser cooling, addressing narrow optical transitions, probing optical clock transitions in atoms, and controlling atomic and some solid state qubit systems 1,2,[4][5][6][7][8][9][10][11] . In addition, this WGM laser can be packaged in a small form factor and thus could have lower sensitivity to environmental noise than standard external cavity diode laser designs.…”

Compact, high power lasers with narrow linewidth are important tools for the manipulation of quantum systems. We demonstrate a compact, self-injection locked, Fabry-Perot semiconductor laser diode with high output power at 493 nm. A high quality factor magnesium fluoride whispering gallery mode resonator enables both high passive stability and 1 kHz instantaneous linewidth. We use this laser for laser-cooling, in-situ isotope purifcation, and probing barium atomic ions confined in a radio-frequency ion trap. The results here demonstrate the suitability of these lasers in trapped ion quantum information processing and for probing weak coherent optical transitions.

“…In addition, the microcavities can be used as a gyroscope [ 23 ]. Using microcavities, it is also possible to create stable compact narrow-band laser systems [ 24 , 25 ] and to generate optical frequency combs [ 26 ] including soliton ones [ 27 ]. These are an important tool for resolving many actual problems; for example, precision spectroscopy [ 28 , 29 ].…”

A measurement system for the detection of a low concentration of nanoparticles based on optical microcavities with whispering-gallery modes (WGMs) is developed and investigated. A novel method based on the WGM broadening allows us to increase the precision of concentration measurements up to 0.005 ppm for nanoparticles of a known size. We describe WGM microcavity manufacturing and quality control methods. The collective interaction process of suspended Ag nanoparticles in a liquid and TiO2 in the air with a microcavity surface is studied.
