    摘要： Embodiments of the present invention relate to an on-chip optical interconnection structure and network. The on-chip optical interconnection structure includes M levels of optical switching devices; and m th -level optical switching devices in the M levels of optical switching devices include 2 m -1 optical switching devices. Each optical switching device in (i-1) th -level optical switching devices in the M levels of optical switching devices is connected to two optical switching devices in i th -level optical switching devices. Two optical switching devices that are in the i th -level optical switching devices and that are connected to a same optical switching device in the (i-1) th -level optical switching devices are connected. The on-chip optical interconnection network is divided into levels, and switching devices connected in a grid manner are formed, so that hierarchical switching may be performed, and conflicts and delays in communication are reduced. In addition, optical switching devices at a bottom layer of the on-chip optical interconnection structure allow faster and more effective communication between computer components without accessing an optical switching device at a higher layer.

    摘要： An optical transmitting apparatus and an electronic device are provided, and relate to the field of optical and electronic device technologies. The optical transmitting apparatus includes: an array light source (401), a collimating lens (402), a rotatable scanning mirror (403), and an optical beam splitter (404). The array light source (401) may include M rows and N columns of light sources, both M and N are positive integers, and an included angle between any column of light sources in the N columns of light sources and any row of light sources in the M rows of light sources is a preset angle. The array light source (401) is located on a first side of the collimating lens (402), a plane on which the array light source (401) is located is perpendicular to an optical axis of the collimating lens (402), and a distance between the plane on which the array light source (401) is located and a center point of the collimating lens (402) is a focal length of the collimating lens (402). The rotatable scanning mirror (403) is located on a second side of the collimating lens (402), and a center point of a reflective surface of the rotatable scanning mirror (403) is on the optical axis of the collimating lens (402). Requirements on a rotation angle of the rotatable scanning mirror (403) in the optical transmitting apparatus are reduced, and utilization of a light beam emitted by the optical transmitting apparatus is improved.
