Fig. 11.11 Optical setup for Raman-based SR. In a P&P configuration, a 785 nm probe pulse and
392 nm pump are temporally synchronized and spatially overlapped into a scanning microscope,
and focused on the sample by a high NA air objective. Detection modalities include both Raman
scattering spectral detection and NPMR. RM: removable mirror. DM: dichroic mirror. BS—beam
splitter. PD—photodiode. LLF—laser line filter. Reproduced with permission from [45], OSA
Fig. 11.12 Response of a silicon Raman emitter to temperature. a Calibration measurements.
Experimental temperature dependence of silicon Raman spectra using a temperature stabilized
heating plate. b The integrated Raman signal for a point emitter as a function of temperature.
Black—integrated changes in Stokes signal. Red—integrated Stokes signal in the ROI (defined in
12a). Note the nonlinear response. Top left inset—focused beams and Si point targets on sapphire
substrate. Reproduced with permission from [45], OSA
