Embodiment Construction

[0034] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0035] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no interveni...

Abstract

The invention discloses a filter fixing member, a manufacturing method of the filter fixing member and a manufacturing method of a compact-type coarse wavelength division multiplexer. The filter fixing member comprises a top surface, a bottom surface opposite to the top surface, and two side surfaces which are connected with the top surface and the bottom surface and are arranged in a mode of being parallel and opposite to each other. The top surface is equipped with multiple optical path grooves which extend along a preset optical path of the compact-type coarse wavelength division multiplexer to form multiple optical path passages. The multiple optical path grooves penetrate the two side surfaces, so that multiple optical path interfaces are formed in the two side surfaces. The two side surfaces are mounting surfaces used for mounting optical devices. Through the filter fixing member disclosed by the invention, a problem that requirements for the side sag of an optical device when side surfaces of the optical device and a substrate are bonded are too high can be avoided so as to improve the qualified rate, a complex operation of precisely adjusting angles of the optical device is removed in production, the operation difficulty is reduced, and the working time is saved.

Description

【Technical field】 [0001] The invention relates to a wavelength division multiplexer, in particular to a filter fixing part and its manufacturing method, and a manufacturing method of a compact wide wavelength division multiplexer. 【Background technique】 [0002] The principle of compact wide wavelength division multiplexer (CCWDM) is to reflect the light beam step by step between the multi-stage filters, and through the filtering of each stage filter, the collimator at each stage can receive the light of each channel wavelength separately. Signal. figure 1 It is a schematic diagram of the optical path of a compact wide wavelength division multiplexer. Such as figure 1 As shown, COM is the optical input port, CH1 to CH8 are the optical output ports of each channel, and Upgrade is the optical output port of the upgrade end. [0003] The fixing method between the filter 1 and the substrate 2 of the traditional compact wide wavelength division multiplexer is that the side of ...
