V Grooved Quantum Wire Laser

4x4 micron Collection NSOM image taken during operation		Thermal Image of the same region

The collection mode NSOM image clearly reveals the V-shaped evanescent field on either side of the Quantum Well Laser. Note that areas with high light intensity are not identical with areas of high thermal intensity. This information can only be uncovered by simultaneous imaging.

These Images were produced using the The MultiView 1000™ and Nanonics Thermal Probes.

Only Nanonics Thermal Probes have a thermal response time under 20us thermal resolution under 10 millidegrees and nanometric spacial resolution.

In the Dual Wire Thermoresistive probe, two platinum wires are stretched through the nanopipette and fused together at their tips. This fused junction has a resistance that is temperature-dependent. This unique tip allows simultaneous measurement of surface topography with thermal conductivity or temperature.
