Controlled Transportation of Light by Light at the Microscale

Semiclassical theory of frequency combs generated by parametric modulation of optical microresonators

“…This result justifies the approximation of a realistic input-output waveguide coupled to microresonator by an internal source used in several publications (see, e.g. [10,[17][18][19]).…”

“…Complementary to sections 2 and 3, in appendix M, we consider the OFC generation in modulated microresonators excited by an internal light source, which is used in many theoretical studies of microresonators (see e.g. [10,[17][18][19]), and find the direct relation between this model and the model of the input-output waveguide used in practice. For the purpose of a more straightforward comparison of the performance of the RTM and SBM, in the main text of this paper we consider the input-output waveguides positioned at the edge of SBMs.…”

Angstrom-precise fabrication of surface nanoscale axial photonics (SNAP) microresonators with a flame

“…Fabrication of such SMRs using approaches previously developed in the SNAP technology [9][10][11][12][13] was challenging. In addition, the unscalable behaviour of cutoff wavelength (figure 2(e)) can be used for the controlled all-optical manipulation of slow whispering gallery light pulses when the propagation of strong control and weak controlled pulses are governed by different axial cutoff wavelength variations [17,18]. Future improvement of our approach will include experimental development and optimization of setups illustrated in figure 1 and modelling of the transient heating processes induced by a flame.…”

Enhancing the impedance matched bandwidth of bottle microresonator signal processing devices

“…In conclusion, we showed that the IM bandwidth of a SNAP BMR signal processing device (in particular, a miniature delay line) can be enhanced by modification of the ERV or, equivalently, the cutoff wavelength variation of the optical fiber. A similar approach can be applied to other BMR-based devices (e.g., dispersion compensators [23] and advanced nonlinear SNAP devices [24]). The deltafunction model used above for the ERV optimization is feasible and may be realized, e.g., with a contact to an optical microfiber.…”
