Description

Technical Field

[0001] The present invention relates to the field of optical communication technology, and in particular to a multi-channel optical path matrix response device. Background Art

[0002] With the rapid development of optical communication technology and the growing demand for large-scale data transmission, especially in data centers, GPU computing clusters and other high-performance computing scenarios, optical networks have an increasingly strong demand for fast response of multi-channel optical paths. In these applications, optical path switching technology, as the core technology for achieving efficient optical path resource allocation, directly affects the system's transmission efficiency and network performance.

[0003] Specifically, the multi-channel optical path switching requirements in existing scenarios mainly include: 1) fast multi-channel optical path switching, that is, realizing fast switching between optical paths of different optical input ends and optical output ends to meet dynamic load scheduling requirements; 2) one-to-many broadcast network switching, that is, realizing simultaneous broadcast transmission from a single optical input channel to multiple optical output channels in the network to support multi-user collaborative computing and data distribution; 3) multi-channel spectral filtering function, that is, flexible and adaptive adjustment of the spectrum of the optical signal of each channel to optimize the transmission quality and channel utilization efficiency.

[0004] In the prior art, the mainstream optical path switching technology mostly adopts optical path switching devices based on micro-electromechanical systems (MEMS), and constructs a multi-channel optical path matrix of the light input end and the light output end by combining the optical path switching units in parallel and cascade.

[0005] However, the prior art still has the following deficiencies in practical applications:

[0006] 1) The switching speed is limited, that is, the mechanical motion characteristics of MEMS components cause them to exhibit response delays and reduced reliability in high-frequency switching scenarios;

[0007] 2) Limited scalability, that is, the complexity of the parallel + cascade structure increases exponentially with the increase in the number of channels, which is difficult to meet the needs of high-density optical networks;

[0008] 3) Single function: Traditional solutions focus more on the on-off switching of optical paths, but have limitations in achieving multi-functional matrix responses (such as spectral modulation, one-to-many broadcasting, etc.). Summary of the invention

[0009] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a multi-channel optical path matrix response device for solving the problems of limited switching speed, limited scalability and single function in the prior art of using MEMS components to achieve optical path switching.

[0034] In one embodiment of the present invention, the amplifying and filtering component is implemented by a semiconductor optical amplifier array, and the operating parameters of the amplifying and filtering component are changed by changing the input current of the semiconductor optical amplifier array.
