Problems solved by technology

Most of the optical switches in the prior art are one-to-two mode, that is, one input terminal and two optional output terminals. If more output terminals are needed, multiple optical switches need to be connected in series, which is not conducive to integration.

Embodiment Construction

[0013] figure 1 is a schematic diagram of the present invention. Such as figure 1 As shown, the present invention includes an input optical waveguide 1, an input collimator 2, a first prism 3, a second prism 4, an output collimator 5 and four output optical waveguides 6-9. The four output optical waveguides 6-9 are arranged vertically from top to bottom. The input optical waveguide 1, the input collimator 2, and the output collimator 5 are sequentially arranged in the horizontal direction; the four optical waveguides 6-9 are placed behind the output collimator 5. The input optical waveguide 1 and the fourth optical waveguide 6 are on the same horizontal line. Both the first prism 3 and the second prism 4 can be moved in or out between the input collimator 2 and the output collimator 5 . The first prism 3 includes a first vertical surface and a first inclined surface; the second prism 4 includes a second vertical surface and a second inclined surface; the inclination angle ...

Abstract

The invention discloses an one-four-optional optical switch which comprises an input optical waveguide, an input collimator, a first prism, a second prism, an output collimator and four output optical waveguides, wherein the input optical waveguide, the input collimator and the output collimator are arranged in sequence in the horizontal direction; the four optical waveguides are placed behind the output collimator; the four output optical waveguides are arranged from top to bottom in sequence in the vertical direction; the input optical waveguide and the fourth optical waveguide are arranged on the same horizontal line; both the first prism and the second prism can move in and out between the input collimator and the output collimator; the first prism comprises a first vertical surface and a first inclined surface; the second prism comprises a second vertical surface and a second inclined surface; the inclination angle of the second inclined surface is greater than the first inclined surface. By adopting the one-four-optional optical switch, the function of one-four-option can be achieved in a single optical switch device, the size of the device can be reduced, and integral manufacturing can be facilitated.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to a one-to-four optical switch. Background technique [0002] An optical switch is an optical device with one or more optional transmission ports, and its function is to physically switch or logically operate optical signals in optical transmission lines or integrated optical circuits. Most of the optical switches in the prior art are in a one-to-two mode, that is, one input terminal and two optional output terminals. If more output terminals are required, multiple optical switches need to be connected in series, which is not conducive to integration. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention discloses a one-to-four optical switch. [0004] Technical scheme of the present invention is as follows: [0005] A one-to-four optical switch, comprising an input optical waveguide, an input collimator, a first prism...
