Abstract
A near-field optical probe has a flat support member having opposed flat surfaces, and a tapered through-hole extends through the support member and terminates at one of the flat surfaces in a narrow aperture. A light collecting layer having a plurality of reflective surfaces is disposed on the support member for collecting and focusing light passing through the narrow aperture. An optical detector disposed above the light collecting layer detects light passing through the light collecting layer.
