An optical interconnection system and method are provided. The system includes two or more basic components that are stacked and interconnected. The basic component includes an optical network layer and an electrical layer, where in each basic component, the optical network layer is electrically interconnected with the electrical layer, and the optical network layer of each basic component is optically interconnected with an optical network layer of an adjacent basic component, and through optical interconnection in three-dimensional space, a limitation on a quantity of stacked electrical layers is reduced, and efficiency of signal transmission is increased.

Optical interconnection system and method

An optical buffer and a method for storing an optical signal using the optical buffer, where the optical buffer includes a first waveguide, a first optical delay waveguide loop and a controller. The first waveguide includes a first arm and a second arm, where a first end of the first arm is an input end of the optical buffer, and a second end of the second arm is an output end of the optical buffer. A second end of the first arm connects to a first end of the second arm. The first optical delay waveguide loop connects to the first arm at a first end using a first optical switch, and a second part of the first optical delay waveguide loop connects to the second arm at a second end using a second optical switch. The controller connects to the first optical switch and the second optical switch respectively.

An annular optical shifter and a method for controlling shift, where the annular optical shifter includes: a first bent straight-through waveguide, connecting an input end and an output end of an optical signal, and configured to transmit, to the output end, the optical signal input from the input end; multiple optical delay waveguide loops, arranged transversely and parallel on two arms of the first bent straight-through waveguide, where the multiple optical delay waveguide loops are configured to temporarily store optical signals; multiple pairs of optical switches, where each pair of optical switches are configured to control on and off of an optical path that is on the two arms of the first bent straight-through waveguide and two sides of an optical delay waveguide loop corresponding to each pair of optical switches; and a controller, configured to implement shift-up or shift-down of the optical signals.

Annular optical shifter and method for shifting optical signal

An interconnection system, an apparatus, and a data transmission method. In the interconnection system, to-be-transmitted data is converted into a data packet in an optical signal form for transmission, and a control packet corresponding to the data packet is transmitted in an electrical signal form and includes routing information of the data packet. When the control packet passes through a switching node, the switching node directly determines, according to the routing information in the control packet, a neighboring node that serves as a next hop, and opens, in the switching node, an optical path used to transmit the data packet. Because no optical-to-electrical or electrical-to-optical conversion needs to be performed on the control packet and the data packet during an entire transmission procedure, problems of an extra delay and power consumption caused by electrical-optical-electrical conversion can be reduced, thereby improving data transmission efficiency.
