Original abstract

We present the comparative study of spatially resolved near-field photocurrent (NPC) spectra for high power laser diode arrays with double quantum well before and after degradation due to the aging process. Subwavelength spatial resolution is established using a single mode fiber probe as an excitation source. The potential of the technique for analyzing microscopic aging processes in optoelectronic devices is demonstrated. The nondestructive quality of this method is a particularly attractive for in-situ analysis of the structures.
