MHz-level self-sustained pulsation in polymer microspheres on a chip

MHz-level self-sustained pulsation in polymer microspheres on a chip

We observe MHz-level periodic self-sustained pulsation (SSP) in the transmission spectrum of a polydimethylsiloxane (PDMS) spherical microcavity on a silicon chip, under a fixed-frequency continuous laser excitation. The SSP results from the strong competition between the thermo-optic a...
