OPTICAL INTERCONNECT OF COMPUTING MODULES

原文（中文）

The present disclosure relates to optical interconnect technology between computing modules, and particularly to a computing module that includes an optical interconnect unit. According to one aspect of the present disclosure, there is provided a computing module, the computing module comprising: a substrate; a data processing unit disposed on a surface of or inside the substrate; a signal switching unit disposed on the surface of or inside the substrate; an optical interconnect unit; and an optical waveguide. In the computing module, optical signal transmission between the signal switching unit and the optical interconnect unit is implemented via the optical waveguide, the optical interconnect unit comprising: a collimating lens array in optical connection with the optical waveguide; a control unit disposed near the collimating lens array; and a microcontroller disposed on the surface of or inside the substrate, wherein the microcontroller is configured to, based on an optical signal intensity measured at the signal switching unit, adjust a refractive index or a position of the collimating lens array via the control unit to improve an optical coupling efficiency between the optical waveguide and the optical interconnect unit.
