Abstract
Abstract In the case of fixing an optical fiber array to a substrate, wherein the optical fiber includes a V-groove substrate having at least one V-groove used for arranging an optical fiber, a fix substrate for fixing the optical fiber in the V-groove, and a pair of guide grooves arranged at both ends of the V-groove through which a guide pin used for a connection is arranged, the guide pin is arranged in the guide groove and the optical fiber array is fixed to the substrate under such a condition that one point of the guide pin is brought into contact with the substrate.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
201 words
A method of fixing an optical fiber array to a receiving substrate, comprising the steps of: providing a receiving substrate including a receiving surface; providing an optical fiber array comprising (i) a V-groove substrate having at least one V-groove receiving at least one respective optical fiber, a pair of guide grooves respectively arranged on opposing lateral sides of the at least one V-groove, and lateral joining surfaces, said guide grooves respectively receiving a pair of guide pins, and (ii) a fix substrate for fixing said at least one optical fiber in said at least one V-groove; and securing said optical fiber array on said receiving substrate such that the joining surfaces of the V-groove substrate are adhered to the receiving substate by an adhesive layer, and each guide pin point-contacts said receiving surface and protrudes to a point beyond said joining surfaces as viewed in cross-section in a plane perpendicular to said receiving surface, wherein said fix substrate is secured to the V-groove substrate so as not to protrude beyond the guide pins as viewed in cross-section in a plane perpendicular to the receiving surface and said at least one optical fiber overlies at least a portion of said receiving surface.
Claim 2
Independent Claim
201 words
A method of fixing an optical fiber array to a receiving substrate, comprising the steps of: providing a receiving substrate including a receiving surface; providing an optical fiber array comprising (i) a V-groove substrate having at least one V-groove receiving at least one respective optical fiber, a pair of guide grooves respectively arranged on opposing lateral sides of the at least one V-groove, and lateral joining surfaces, said guide grooves respectively receiving a pair of guide pins, and (ii) a fix substrate for fixing said at least one optical fiber in said at least one V-groove; and securing said optical fiber array on said receiving substrate such that the joining surfaces of the V-groove substrate are adhered to the receiving substate by an adhesive layer, and each guide pin point-contacts said receiving surface and protrudes to a point beyond said joining surfaces as viewed in cross-section in a plane perpendicular to said receiving surface, wherein said fix substrate is secured to the V-groove substrate so as not to protrude beyond the guide pins as viewed in cross-section in a plane perpendicular to the receiving surface and said at least one optical fiber overlies at least a portion of said receiving surface.
Claim 3
Dependent Claim
46 words
The method according to claim 1, wherein an optical element having an optical axis is fixed on said receiving substrate, and the optical axis of said optical element is aligned with the optical axis of said at least one optical fiber of said optical fiber array.
Claim 4
Dependent Claim
31 words
The method according to claim 2, wherein said optical element comprises an element from the group consisting of an optical waveguide element, a light receiving element, and a light emitting element.
Claim 5
Dependent Claim
33 words
The method according to claim 1, wherein a plurality of said optical fiber arrays are fixed to the receiving substrate and the same guide pin is used for connecting said optical fiber arrays.
Claim 6
Dependent Claim
27 words
The method according to claim 1, wherein the optical axis of said at least one optical fiber is aligned with a center position of said guide pin.
