a Measured and simulated optical transmission spectra. b Simulated transmission oscillation spectrum. c Simulated temperature dynamics in both silica and PDMS. d Calculated resonance wavelength (λr), probe wavelength (λp), and the associated variation in the detuning. Zero detuning is marked by a dot-dashed line (black) in (d)70. Reprinted with permission from ref. 70 [OSA The Optical Society]
