Abstract

Microcavities have since been characterized in the frequency domain. In particular, high resolution spectroscopy of scattered light has been extensively used to identify high-Q modes (such as Whispering Gallery Modes, WGM) and estimate their quality factors. Similarly, Lorenz-Mie theory is usually applied to microcavities in the stationary regime.¹ Modes can then fulfill the requirements such as orbit closing and phase matching conditions (also with the external fields). Very few studies have been dedicated to transient behaviors,² where the excitation is much shorter than the modes roundtrip times. This latter case can be represented by ballistic motions of wavepackets within resonators, that are much larger.³
