We study temperature dependence of SiC coherent thermal sources.
- class="label">•
We couple experimental SiC optical data with reference literature׳s grating.
- class="label">•
Gratings are optimized to have best emission peak for each temperature.
- class="label">•
An example of narrow IR emitter for a large range of temperatures is shown.

We explain this in the light of surface wave physics and dispersion relation.
