Document Type and Number:
Japanese Patent JP3563360
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an optical device, optical communication parts and optical transmission device such that the structure is simple and the cost is reduced compared with conventional ones.
SOLUTION: Input/output optical fibers 1, 10, 13, ferrules 2, 9, 12 for holding these fibers, and lenses 3, 8, 11 having an outer diameter equal to those of the ferrules are arranged on a V-grooved base plate 4 on which an optical functional element 6 is disposed; as a result, simply structured and 1 cost-reduced optical communication parts can be provided. Bringing the lens into contact with the end of the ferrule dispenses with adjustment in the focal direction of the lens, while arranging the ferrule and the lens on the V-groove 7 unnecessitates alignment of the optical axes.
