Problems solved by technology

[0005] In the prior art, the integration of lasers in silicon photonics platforms is very difficult, especially when the integration space is limited, the number of lasers that can be integrated is severely limited, because a laser can only emit light waves of a single wavelength, so, As a result, the number of carriers that can be provided in the silicon photonics platform is greatly limited

Abstract

A method and device for conducting data transmission, which belong to the technical field of optical interconnection of chips. The method comprises: acquiring elliptically polarized light; conducting polarization beam splitting on the elliptically polarized light, and obtaining first linearly polarized light and second linearly polarized light which form the elliptically polarized light and are perpendicular to each other in vibration directions; and respectively taking the first linearly polarized light and the second linearly polarized light as carriers to conduct data transmission. The number of carriers capable of being provided in an optical communication platform can be increased.

Description

technical field [0001] The invention relates to the technical field of chip optical interconnection, in particular to a method and device for data transmission. Background technique [0002] With the rapid development of computer technology, multi-core processors have gradually replaced single-core processors and become the mainstream processors in the market. In order to reduce the size of the processor, a silicon photonics platform was introduced to transmit data between cores through light waves. [0003] In a silicon-optical platform, a laser array is generally used as a light source, and each laser emits a light wave of a certain wavelength as a carrier for data transmission. Different cores can modulate the data to be sent on different carriers through modulators, or they can Data sent by other cores on each carrier is received by the probe. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems i...
