NEAR-FIELD PROBE WITH GUIDE AND ITS MANUFACTURING METHOD, OPENING CREATION METHOD, AND NEAR-FIELD SPECTROGRAPH AND OPTICAL HEAD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To create the opening of an optical fiber probe used for a technique using a near field, and to improve distance control.;SOLUTION: The near-field probe 2 with a guide comprises a core 6 for guiding light and a cladding 4 to achieve the purpose. The cladding 4 for surrounding the periphery of the core 6 has a recess 4a recessed nearly in a hemispherical shape. The tip of the core 6 has a sharped sharp section 6a. The end face of the flat cladding 4 is set to be a guide surface 8. The guide surface 8 is pressed against a sample and a flat plate for opening. As a result, distance is controlled and the opening is created.;COPYRIGHT: (C)2004,JPO
