Pluggable planar optical waveguide device and manufacturing method thereof

Abstract

The invention relates to a pluggable planar optical waveguide device and a manufacturing method thereof. The pluggable planar optical waveguide device comprises a planar optical waveguide chip, an optical component and a connecting insertion core both connected with two ends of the chip respectively; the optical component and the connecting insertion core are internally provided with optical fibers corresponding to waveguides of the planar optical waveguide chip respectively, and the optical fibers are precisely butted with the waveguides one by one; and a connector is arranged on an end face outside the connecting insertion core. According to the invention, the size of the device is reduced, optical fibers exposed outside the device are reduced or prevented from being exposed outside the device, production links are reduced, the production cost is lowered, the assembly space for a customer is greatly saved, operations of the customer are facilitated, and operational and maintenance cost is lowered.

Description

technical field [0001] The invention relates to a planar optical waveguide device and a manufacturing method thereof, in particular to a pluggable planar optical waveguide device and a manufacturing method thereof. Background technique [0002] Due to the advantages of small size, high stability and reliability, and lower mass production costs, planar optical waveguide devices have increasingly replaced traditional micro-optical or other discrete devices, and play an increasingly important role in optical fiber communication systems and networks. more important role. [0003] Commercial planar optical waveguide devices usually use optical fiber as the medium for signal input and output, and are connected to links or devices by fusion splicing or connector splicing during application. The fusion splicing method requires an expensive optical fiber fusion splicing machine. Relatively speaking, the connector is cheap and easy to operate, and is welcomed by end users. attached ...

Problems solved by technology

The disadvantage of this structure is: the external size of the module box body 21 is large, and a single connector 23 takes up a lot of space, which cannot reflect the advantages of the small size of the planar optical waveguide device (in a typical 1x8 planar optical waveguide optical power splitter, that is, the packaging shell One end of 32 is an optical fiber 31, the other end is an 8-core ribbon optical fiber 33, and the size of the basic packaging shell 32 is 40 mm long, 4 mm wide, and 4 mm high), as attached image 3 shown

However, the disadvantage of this structure is that the product has bare optical fibers, and customers need to carefully manage the optical fibers during use, and the optical fibers are easily damaged during use and operation, which brings difficulties to use and operation.

Generally speaking, the production processes of these commonly used structures are lengthy and complicated, with many turnover links and high material consumption, and each has its own disadvantages when applied on the client side.
