Fig. 3. (a), (b) Transmission spectra of the SIMRR system at two different applied electrical powers of the microheater: P=0 (black lines), P=0.063 W (red lines). The green area highlights the change of transmission spectrum analyzed below. The insets show the expanded transmission spectra of the green area.
