Embodiment Construction

[0027] Such as Figure 4 As shown, the optical bench according to the preferred embodiment of the present invention includes a base 100; input and output optical fibers 120a, 120b, 150a and 150b distributed on the base 100 with predetermined gaps, used to guide input and output beams respectively; And output elements 130a, 130b, 160a and 160b, arranged on the substrate in a staggered form, connected with input and output optical fibers 120a, 120b, 150a and 150b; and a plurality of micromirrors distributed on the substrate in a matrix form 140, for reflecting the light beams input from the optical input elements 130a and 130b to predetermined channels.

[0028] In the optical bench configured as above, light beams emitted from a light source (not shown) enter the input optical fibers 120a and 120b, then enter the optical input elements 130a and 130b, and are reflected by the micromirror 140. The light beams reflected by the micro mirror 140 are output through the optical outpu...

Abstract

The invention discloses an optical bench with an improved structure, wherein the misalignment tolerance of the optical element increases with the shortening of the optical path. The optical bench includes: a base, input and output optical fibers placed on the base with a predetermined gap, and the far ends of the input and output optical fibers are "zigzag" for guiding the input and output beams; input and output elements are arranged in each The far ends of the input and output optical fibers are used to gather and / or disperse the input and output light beams; and a plurality of micro mirrors are used to receive the input light beams from the optical input element and reflect the received input light beams to predetermined channels. The optical path is shortened in the optical bench, so the misalignment tolerance of the optical components is increased and the assembly cost is reduced. The optical bench in the invention has low insertion loss and maximum coupling efficiency.

Description

technical field [0001] The present invention relates to an optical bench, and more specifically relates to an optical bench with improved structure, wherein the optical path is shortened and the misalignment tolerance of optical elements is increased. Background technique [0002] Currently, as the amount of data transmitted by the optical communication network increases, the data transmission mode of the optical communication system has changed to a wavelength division multiplexing transmission mode (WDM). Since this wavelength division multiplexing transmission system WDM requires the connection between networks, the optical cross-connector, that is, the optical bench, becomes a necessary component of the wavelength division multiplexing transmission system. [0003] In traditional optical benches, such as figure 1 As shown, a plurality of micro-mirrors 40 are distributed on the substrate 10 to form a matrix, and a plurality of input optical fiber...
