Problems solved by technology

[0005] (2) The coupling between the optical interconnection layer and the optical transceiver module. The light in the interconnection layer and the light in the optical transceiver module form an angle of 90°. This coupling often uses air as the medium, so it is easy to generate a large insertion loss
[0008] Although this structure is simple and intuitive, it also has certain limitations, and its data transmission can only be from one chip to another; for example figure 2 , a single signal source can only transmit the signal from A to C. If it is necessary to transmit the signal from A to D when C is idle, if it is transmitted from A or C to D in the form of electrical interconnection, then it is The meaning of optical interconnection is lost; if a set of IC drive circuit and VCSEL is reconfigured because of the needs of D, the signal source and structure will be repeated, increasing the overall complexity, and the same is true for B

Embodiment 1

[0033] The structural principle of this embodiment is as Figure 6 As shown, it includes a light emitting module 1 , a switch / output module 2 , an optical waveguide channel 3 , an upper substrate 4 , an outer layer of an optical waveguide 5 , and a lower substrate 6 . The switching / output module at B is in an open state in this embodiment, so that the optical signal is reflected by a specular surface at B. In this case, B is an output terminal that requires an optical signal. The modules involved in this communication include the light emitting module 1 at A, the switch / output module 2 at B, and the optical waveguide path 3 between A and B.

Embodiment 2

[0035] The structural principle of this embodiment is the same as that of Embodiment 1, the difference is that the output terminal becomes the C terminal, such as Figure 7 As shown, the switching / output module at B is in a closed state in this embodiment, allowing the optical signal to pass through smoothly, while the switching / output module at C is open, so that the optical signal is mirror-reflected at C. In this case Below, C is the output terminal that requires optical signals, and the principle is the same as above. The modules participating in this path include the light emitting module 1 at A, the switch / output module 2 at C, and the optical waveguide path 3 between A and C.

Embodiment 3

[0037] The structural principle of this embodiment is the same as that of Embodiment 1, the difference is that the output end becomes an N end, such as Figure 8 As shown, all switching / output modules between A and N are in a closed state in this embodiment, allowing the optical signal to pass through smoothly, while the switching / output module at N is opened, so that the optical signal is mirror-reflected at N, In this case, N is an output terminal that requires an optical signal, and the principle is the same as above. The modules participating in this path include the light emitting module 1 at A, the switch / output module 2 at N, and the optical waveguide path 3 between A and N.

[0038] The invention provides an optical waveguide communication device with a switchable path, which increases the flexibility of the receiving end, and can make the photoelectric communication more convenient and improve the efficiency when needed.

Abstract

The present invention discloses a path-switchable optical waveguide communication device. The optical waveguide communication device comprises an upper substrate (4), an optical waveguide outer layer(5), a lower substrate (6), a light emitting module (1), a switching / output module (2) and optical waveguide passages (2). The switching / output module (2) can be controlled to be closed and opened, sothat the path of optical signals can be changed; when the switching / output module (2) is closed, the optical signals can pass through the switching / output module (2) and enter an optical waveguide ofa next stage; and when the switching / output module (2) is opened, the optical signals cannot enter the optical waveguide of the next stage, and the direction of the optical signals is changed, and the switching / output module (2) receives the optical signals and outputs electric signals. According to the path-switchable optical waveguide communication device, the path of the optical signals can bechanged through controlling the switching / output module (2), so that different receiving ends can be switched according to needs, and therefore, the flexibility of optical communication is improved.

Description

technical field [0001] The invention belongs to the technical field of photoelectric interconnection, in particular, it is applied in the optical waveguide communication structure to realize the switchable path. Background technique [0002] With the continuous improvement of people's requirements for high-speed data transmission, the traditional electrical interconnection between boards has developed to a bottleneck. Coupled with its own disadvantages, gradually unable to meet our requirements. But if optical interconnection is adopted, all this can be easily solved. In the 1960s, the birth of lasers led to the emergence of a series of new disciplines such as semiconductor electronics, guided wave optics, and nonlinear optics. In the 1970s, due to the major breakthroughs in semiconductor laser and optical fiber technology, it led to the vigorous development of optical information science and technology represented by optical information processing, optical fiber sensing, ...
