Abstract
A low-cost, data-fitting-free robust methodology configured to distinguish the coupling condition of an arbitrary resonance, applicable in one example to a micro-resonator of a multi-micro-resonator optical integrated circuit. The method includes registering the resonator cavity response to a rapid-phase shift of the on-resonance pump field. From the registered feature of the time-dependent transmission characteristic acquired with an optical detector, the sign of a difference between the values of intrinsic loss of the cavity and the coupling rate (γ−γ) is directly read out, thereby resulting not only in a more accurate estimation of the intrinsic loss as compared with related art, but also in facilitating practically-realizable inspection of massively integrated photonic platforms with micro-resonators.
