要旨

Real-time characterization of microresonator dynamics is important for many applications. In
particular it is critical for near-field sensing and understanding light-matter interactions. Here,
we report camera-facilitated imaging and analysis of standing wave patterns in optical ring
resonators. The standing wave pattern is generated through bi-directional pumping of a
microresonator and the scattered light from the microresonator is collected by a short-wave
infrared (SWIR) camera. The recorded scattering patterns are wavelength dependent, and the
scattered intensity exhibits a linear relation with the circulating power within the microresonator.
By modulating the relative phase between the two pump waves, we can control the generated
standing waves’ movements and characterize the resonator with the SWIR camera. The
visualized standing wave enables subwavelength distance measurements of scattering targets
with nanometer-level accuracy. This work opens new avenues for applications in on-chip nearfield
(bio-)sensing, real time characterization of photonic integrated circuits and backscattering
control in telecom systems.
