Abstract:
High resolution surface temperature maps of a slotted
surface grating laser operating at approx. 1550 nm are obtained by
means of CCD-thermoreflectance imaging. The resolution is such
that the temperature of the 2 μm wide ridge can be determined.
Experimental temperature profiles along the ridge and in the lat-
eral direction are provided. A 2D numerical model is developed to
simulate the steady state thermal distributions in the laser. There
is good agreement between the experiment and simulation. This
technique allows for high-resolution imaging and will be useful
where hot spots occur on laser devices.
