Abstract
A near field optical microscope with a scanning area up to 1 mmX1 mm w as demonstrated. The scanning element is the tapered fiber probe and a cylindrical lens is used to focus the feedback laser. Instead of the vibrational amplitude, the vibrational angle signal is used to regulat e the distance between the probe and sample. The microscope was employ ed to map out the evanescent wave on a channel waveguide. (C) 1998 Ame rican Institute of Physics. [S0034-6748(98)00510-3].
