What this work contributes
Demonstrates micrometer-scale motion of a movable waveguide coupled to an optical microresonator using milliwatt-level optical input. The measured force is used to make a tunable optical filter, illustrating a concrete commercial component pathway for boundary-mediated optical forces.
Where the evidence stops
This is controlled relative motion of supported components, not thrust of an isolated optical assembly. The paper's model does not permit unlimited force from increasing cavity Q; mode volume and coupling conditions matter.
