A picosecond time-resolved photoluminescence microscope with detection at wavelengths greater than 1500 nm
We describe a picosecond resolution time-resolved photoluminescence microscope with high detection sensitivity at wavelengths extending beyond 1500 nm. The instrument performs time-correlated single photon counting using an InGaAs/InP single photon avalanche diode as a detector, and provides tempora...

| description | We describe a picosecond resolution time-resolved photoluminescence microscope with high detection sensitivity at wavelengths extending beyond 1500 nm. The instrument performs time-correlated single photon counting using an InGaAs/InP single photon avalanche diode as a detector, and provides temporal resolution of less than 300 ps (full width at half maximum) and spatial resolution down to 4 μm at a sample temperature between 4 and 300 K. Analysis of noise characteristics indicates the ability to measure the excess carrier lifetimes of semiconductor devices with excited carrier densities of less than 1014cm-3. © 2001 American Institute of Physics. |
