MANUFACTURING METHOD OF NEAR FIELD PHOTOPROBE, NEAR FIELD OPTICALPROBE, NEAR FIELD OPTICAL MICROSCOPE, NEAR FIELD LIGHT FINE PROCESSING DEVICE AND NEAR FIELD OPTICAL RECORD PLAYBACK DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a near field opticalprobe which can be manufactured at low cost by simple process, a near field opticalprobe, a near field optical microscope, a near field light fine processing device and a near field optical record playback device.;SOLUTION: In a manufacturing method of the near field opticalprobe for manufacturing the near field opticalprobe with an optical minute opening in the top of the probe sharpened by processing an optical fiber, the optical fiber which has a core part and clad part whose materials are different in etching rate respectively for etching solution is used as the optical fiber, the top of the optical fiber is sharpened by the invasion to the etching solution, on the other hand, the core part is exposed by removing the clad part by the etching.;COPYRIGHT: (C)2002,JPO
