Patent ID: 8490210

Claim:
An optical apparatus, comprising: a substrate; and a probe module array constituted of a plurality of probe modules disposed at a uniform distance on the substrate, wherein each of the plurality of probe modules includes: a probe tip which protrudes in a truncated shape having a narrower plan surface and a wider plan surface relatively wider than the narrower plan surface, of which a metal thin film is coated on a surface, and of which an aperture of nm diameter is included in a portion of the metal thin film on a central portion of the narrower plan surface; a spring structure disposed at a perimeter of the probe tip and configured to maintain a gap distance with the probe tip and a film to be exposed; a dielectric filled within the aperture; and a protection layer disposed on the narrower plan surface of the probe tip, wherein an optical transport path is included within the probe tip to be connected to the aperture.
