Abstract

We demonstrate a thermally tunable Surface Nanoscale
Axial Photonics (SNAP) platform. Stable tuning is
achieved by heating a SNAP structure fabricated on the
surface of a silica capillary with a metal wire positioned
inside. Heating a SNAP microresonator with a uniform
wire introduces uniform variation of its effective radius
which results in constant shift of its resonance wavelengths.
Heating with a nonuniform wire allows local
nanoscale variation of the capillary effective radius,
which enables differential tuning of the spectrum of
SNAP structures as well as creation of temporary SNAP
microresonators that exist only when current is applied.
As an example, we fabricate two bottle microresonators
coupled to each other and demonstrate differential tuning
of their resonance wavelengths into and out of degeneracy
with precision better than 0.2 pm. The developed
approach is beneficial for ultraprecise fabrication
of tunable ultralow loss parity-time symmetric, optomechanical,
and cavity QED devices.
