Problems solved by technology

But this erbium-doped slab waveguide device 2 is not suitable for use as a waveguide amplifier because of its polarization dependence, and it not only generates optical amplification in the required linear direction, but also generates optical amplification in other directions of the plane, thereby increasing optical loss.
In addition, the manufacturing cycle of the waveguide device is longer, resulting in increased cost

Abstract

The polymer-based waveguide device for light amplifier and laser waveguide includes base body, inner polymer coating on the base body, channel waveguide set on the inner polymer coating and outer polymer coating covering the inner polymer coating and the channel waveguide. The channel waveguide is made with at least one kind of RE metal ion doped composition capable of being excited to generate laser. The preparation process of the waveguide device includes the steps of: making a base body; painting the inner polymer coating on the base body and drying to cure; painting the second polymer with dissolved RE metal ion doped composition and selectively curing and etching to form the channel waveguide; and painting outer polymer coating and drying to cure. The waveguide device has excellent light amplifying and transmitting function.

Description

【Technical field】 [0001] The present invention relates to a waveguide device used as an optical amplifier or a laser waveguide and its manufacturing method, especially a polymer-based waveguide device used as an optical amplifier or a laser waveguide and its manufacturing method. 【Background technique】 [0002] In the process of making optical fiber, rare earth ions are doped into the optical fiber core as a gain medium, and the optical signal can be directly amplified by using pump light to provide optical gain. In the manufacture of optical fibers, the optical fibers made by doping erbium ions into the core are erbium-doped optical fibers, which are commonly used in Erbium-Doped Fiber Amplifier (EDFA), and can be directly connected to the The signal light is amplified and is the main component to provide optical gain. [0003] U.S. Patent No. 5,982,973 discloses an erbium-doped slab waveguide device 2, please refer to image 3 , which consists of a substrate 21, an inner ...
