Nanoscale coherent imaging of photonic structures by PSTM [PDF]
, 2000 We present an alternative instrument to map local optical field distributions: a photon scanning tunneling microscope (PSTM). In a PSTM a near-field optical fiber probe is used to frustrate the evanescent field above an integrated optical device.
