detailed description

In order to make the technical means, creative features, achievement goals and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

Referring to FIG. 1 to FIG. 6 , the present invention provides a planar waveguide C-groove substrate comprising a substrate 100 and a substrate cover 200 .

The substrate 100 is used for accommodating the optical fiber 300. The whole is a rectangular parallelepiped. A plurality of sequentially connected C-shaped grooves 110 are formed on the upper surface of the substrate 100.

Each C-shaped groove 110 can be placed with an optical fiber 300. For ease of placement, the optical fiber 300 is buried more in the C-shaped groove 110, and the force is uniform. The C-shaped groove 110 is an inscribed circle with an arc of 1.3. And the deviation of each C-shaped groove 110 is controlled within 0.01.

In addition, at the junction of the two adjacent C-shaped grooves 110 is a planar structure 130, in particular, the connection of the adjacent two C-shaped grooves 110 can be flattened, thereby preventing the fiber 300 from being punctured at the joint.

Furthermore, a stepped recess is provided on the C-shaped groove 110 on both side edges of the substrate 100. 120, the recess 120 is located between the C-shaped groove 110 and the upper surface of the substrate 100, and the recess 120 facilitates the placement of the substrate cover 200.

The substrate 100 provided by the utility model is made of a light absorbing material or a light attenuating glass material having a refractive index of 1.4 to 1.55, and the overall light absorption rate is between 20 dB and 40 dB.

The substrate cover 200 is made of a light absorbing material or a light attenuating glass material, and has a rectangular parallelepiped shape as a whole, and is covered on the substrate 100 for protecting the optical fiber 300 on the substrate, and is disposed on the lower surface of the substrate cover 200. There is a boss 210;

The boss 210 and the region of the substrate 100 on which the C-shaped groove 110 is opened correspond to each other, which can cover it, and when the substrate cover 200 covers the substrate 100, the sides of the two sides of the boss 210 are just placed in the concave table. 120, such that the boss 210 can cover the optical fiber 300 on the C-shaped groove 110 without contacting the optical fiber 300, and crushing the optical fiber 300.

In addition, in order to further improve the connection stability between the substrate 100 and the substrate cover 200, a first small chamfer 111 is provided at the tail of each C-shaped groove 110, and a first small chamfer is provided at the tail of the boss 210. The second small chamfer 211 is matched with the 111, so that when the optical fiber 300 is placed in the C-shaped groove 110, the first small chamfer 111 can be positioned, and when the substrate cover 200 is covered on the substrate 100, the second can be passed through the second The small chamfer 211 is positioned and fixed in cooperation with the first small chamfer 111 to enhance the connection stability between the substrate 100 and the substrate cover 200, and the optical fiber 300 is fixed between the substrate 100 and the substrate cover 200.
