Abstract

Disclosed are an on-chip optical network system and a light power control method. The on-chip optical network system comprises a light source, an optical waveguide, a controller, an optical power distributor and a modulator, wherein light waves emitted by the light source are transmitted to the optical power distributor via the optical waveguide; the optical power distributor is used for obtaining a light wave from the optical waveguide and transmitting the obtained light wave to the modulator; and the controller is used for calculating a first light power and controlling the light power obtained by the optical power distributor from the optical waveguide to be a light wave of the first light power, the first light power being the sum of the first light power loss generated when the light wave is transmitted between the optical power distributor and the modulator and a light power required by the modulator. The system realizes the distribution according to needs of a light power, thereby reducing conditions of excessive light powers obtained by the modulator, and reducing the power consumption of the system.

Description

technical field [0001] The invention relates to the field of on-chip optical network technology, in particular to an on-chip optical network system and an optical power control method. Background technique [0002] Judging from the current development status of the processor industry, integrating more and more processor cores is currently recognized as a way to continue Moore's Law. One of the main problems faced by multi-core processors is how to realize effective and fast communication between multiple processor cores. To solve this problem, both the industry and academia have begun some attempts to introduce optical interconnects into on-chip interconnects / networks. [0003] In the prior art, an on-chip optical network system may include the following components: a light source, an optical waveguide, a modulator, and the like. Among them, the light source injects the light wave generated by it into the optical waveguide, and the optical waveguide is used to transmit the ...
