SNAP microwave optical filters

M. Sumetsky

Abstract: If the originally flat bottom of a wide quantum well with multiple eigenstates is periodically modulated, its eigenvalues rearrange into denser groups separated by wider gaps. We show that this effect, if implemented in an elongated bottle microresonator [also called a surface nanoscale axial photonics (SNAP) microresonator] allows us to design microwave photonic tunable filters with an outstanding performance.

The fabrication of surface nanoscale axial photonics (SNAP) microresonators, utilizing the approach of electric arc discharge (EAD), is accomplished, achieving a precision at the angstrom level. This paper thoroughly investigates the effects that discharge intensity and discharge duration have on SNAP microresonators, respectively, through the manipulation of relevant discharge parameters. The results indicate that, within a specified range of discharge intensity, a linear relationship is observed between the effective radius variation (ERV) and the discharge intensity, characterized by a slope of 0.325 nm/intensity unit. As the discharge duration is extended, the ERV gradually increases, eventually reaching a saturation value, which is inherently determined by the discharge intensity. Additionally, as the discharge intensity (or time) continues to increase, a “convex–concave–convex” shape is observed on the fiber, providing a method for fabricating bat microresonators. These discoveries derived from our study contribute toward providing a strong foundation for the progressive enhancement and refinement of EAD-based SNAP fabrication techniques.

Dispersion Tailoring and Four-Wave Mixing in Silica Microspheres with Germanosilicate Coating

et al. 2021

Optical whispering gallery mode microresonators with controllable parameters in the telecommunication range are demanded for diverse applications. Controlling group velocity dispersion (GVD) in microresonators is an important problem, as near-zero GVD in a broad wavelength range could contribute to the development of new microresonator-based light sources. We demonstrated theoretically near-zero dispersion tailoring in the SCL-band in combination with free-spectral range (FSR) optimization for FSR = 200 GHz and 300 GHz in silica glass microspheres with micron-scale germanosilicate coating. As an illustration of a possible application of such a GVD, we also performed a theoretical study of degenerate four-wave mixing (FWM) processes in the proposed microresonators for pumping in the SCL-band. We found that in some cases the generation of two or even three pairs of waves–satellites in a FWM process is possible in principle due to the specific GVD features. We also determined optimal microresonator configurations for achieving gradual change in the satellite frequency shift for the pump wavelengths in the SCL-, S-, CL-, C-, and L-bands. The maximum obtained FWM satellite tunability span was ~78 THz for a pump wavelength change of ~30 nm, which greatly exceeds the results for a regular silica microsphere without coating.
