“…Raman scattering was also observed in solid crystalline [463][464][465][466] and amorphous [323,461,[467][468][469] WGM resonators, as well as studied theoretically [470]. The interest in this process is stimulated by a wide range of potential application for Raman lasers.…”

Optical whispering gallery modes (WGMs) derive their name from a famous acoustic phenomenon of guiding a wave by a curved boundary observed nearly a century ago. This phenomenon has a rather general nature, equally applicable to sound and all other waves. It enables resonators of unique properties attractive both in science and engineering. Very high quality factors of optical WGM resonators persisting in a wide wavelength range spanning from radio frequencies to ultraviolet light, their small mode volume, and tunable in-and out-coupling make them exceptionally efficient for nonlinear optical applications. Nonlinear optics facilitates interaction of photons with each other and with other physical systems, and is of prime importance in quantum optics. In this paper we review numerous applications of WGM resonators in nonlinear and quantum optics. We outline the current areas of interest, summarize progress, highlight difficulties, and discuss possible future development trends in these areas.

“…However, the fabrication of micron-sized resonators from crystalline materials typically requires fairly labor-intensive processes such as mechanical polishing or multi-step etching to achieve high quality surfaces [4,6]. In contrast, resonators fabricated from micrometer sized glass fibers can be produced via a simple heating process that makes use of surface tension reshaping to form resonators with surface roughness values σ <1 nm [7,8]. Of these fiber resonators, much focus has been placed on devices that are fashioned from the extremely low loss silica platforms so that Q factors above 10 7 can be readily achieved [7,9].…”

Kerr nonlinear switching in a hybrid silica-silicon microspherical resonator

et al. 2015

A hybrid silicon-core, silica-clad microspherical resonator has been fabricated from the semiconductor core fiber platform. Linear and nonlinear characterization of the resonator properties have shown it to exhibit advantageous properties associated with both materials, with the low loss cladding supporting high quality (Q) factor whispering gallery modes which can be tuned through the nonlinear response of the crystalline core. By exploiting the large wavelength shift associated with the Kerr nonlinearity, we have demonstrated all-optical modulation of a weak probe on the timescale of the femtosecond pump pulse. This novel geometry offers a route to ultra-low loss, high-Q silica-based resonators with enhanced functionality.

“…Thus, in comparison with Brillouin scattering or FWM, phase matching is automatically satisfied; this makes Raman lasing in WGRs relatively easy to implement. The ultrahigh optical Q in WGRs guarantees a very low Raman lasing threshold and even cascaded processes can be achieved, as has been demonstrated in silica microspheres [6,7], microtoroids [8,9], chalcogenide microspheres [10,11], and PDMS (polymer) WGRs [12]. Raman lasing in WGRs can be very useful for sensing applications since (i) it does not require a dopant in the resonator's material and (ii) it decreases the effective linewidth of the WGM through Raman gain.…”

We report on the fabrication of an ultrahigh quality factor, bottle-like microresonator from a microcapillary, and the realization of Raman lasing therein at pump wavelengths of $1.55~\mathrm{\mu m}$ and $780~\mathrm{nm}$. The dependence of the Raman laser threshold on mode volume is investigated. The mode volume of the fundamental bottle mode is calculated and compared with that of a microsphere. Third-order cascaded Raman lasing was observed when pumped at $780~\mathrm{nm}$. In principle, Raman lasing in a hollow bottle-like microresonator can be used in sensing applications. As an example, we briefly discuss the possibility of a high dynamic range, high resolution aerostatic pressure sensor
