Multiprobe Optical and Thermal Profiling
The MultiView 4000™ System simplifies the task of optically and thermally profiling on-line an optoelectronic device. Seen in these images (above) are the optical distribution of light in a quantum wire laser (NSOM) and the thermal distribution around the laser. The image below includes the p contact region in the thermal image. As can be seen, the thermal and light distribution bear no correlation to one another, but rather the thermal distribution is bowed towards the p contact where electrical charge is injected. |
