摘要：Micro-optic filtering devices and the method of making the same are described. In one aspect, the invention is related to techniques of obtaining low-loss coupling optics, packaging structure and process to secure components constituting a micro-optic fiber device. To support and fix various components in a fiber optic device, tubes are used to facilitate the manufacturability of these optical devices. These tubes may be metal tubes or glass tubes.

主权项：1. A method for manufacturing an optical device, the method comprising: attaching a filter to a first lens by a type of adhesive to form a first assembly; aligning the first assembly with a dual fiber pigtail in such a way that an insertion loss between the first assembly and the dual fiber pigtail is minimized when a light beam travels from one fiber to another in the dual fiber pigtail, wherein the first assembly and the dual fiber pigtail are bonded to form a dual fiber collimator; inserting the dual fiber collimator into a first tube until the first tube covers the dual fiber pigtail; sliding a second tube over the first tube, wherein the second tube is substantially longer than the first tube to encapsulate the first tube and the first assembly; attaching a second lens and a single fiber pigtail by a type of adhesive to form a second assembly; aligning the first and the second assemblies to achieve optimal beam lateral position matching and tilting angle alignment so as to minimize an insertion loss between the first and the second assemblies; and bonding together the first tube and a third tube containing the second lens to form the optical device, wherein the first tube and the third tube are different in diameters so that the second tube and the third tube are connected coaxially.
