Spectral Investigation of Laser Structures using NSOM Experiment

We present for the first time the local spectral analysis of quantum well laser devices recorded in the near-field region. The distribution of mode spectra along and active region was scanned near-field scanning optical miecroscopy (NSOM). This experimental technique in combination with the near-fie...

Zusammenfassung:We present for the first time the local spectral analysis of quantum well laser devices recorded in the near-field region. The distribution of mode spectra along and active region was scanned near-field scanning optical miecroscopy (NSOM). This experimental technique in combination with the near-field analysis of optical field could be effective optical tool for the final diagnostic of optical waveguide and laser device.
