Optical interconnects based on MPS
Optical interconnects based on multi-layer polymer waveguide systems (MPWS).
Interconnects optical communication based on a multilayer polymer waveguide systems (MPS) has significant advantages compared with metallic conductors, such as speed of data transfer (5 Gbps) and compatible.
Description:
Technology of fiber optic connections in recent years has been increasingly used to deploy communications networks on short distances, in particular for connecting servers in data centers. Currently, the optical conductors are already ready to conquer the super short distance of the microelectronic world. The major problem is the communication latency when transferring data between the multiple cores, cache memory and other functional microelectronic components. New systems require high-speed interconnects (i.e., interconnects optical communication), which will significantly speed up data transfer and provide an effective payload processor and so on microelectronic components.
Due to the much higher bandwidth compared with metallic conductors, fiber optic connections more efficient for data transfer from Board to Board, from chip to chip and from element to element within the chip. High-speed interconnects, including optical communication, are one of the most important conditions for building a promising high-speed computing systems. They allow to eliminate bottlenecks of computing systems and improve their performance.
Interconnects optical communication based on a multilayer polymer waveguide systems (MPS) has significant advantages compared with metallic conductors, such as speed of data transfer (5 Gbps) and compatible.
The basis MPVS is a symmetric planar waveguide, allowing to channel the electromagnetic energy in the optical range. Thus self-consistent (continuous) in the longitudinal direction distribution of electric or magnetic fields in the waveguide channel is possible only for certain values of the angles of radiation propagation and the corresponding effective refractive indices.
Stability of optical density, refractive indices, the level of attenuation of an optical signal transmission rate information via a single waveguide channel MPS is provided by selection of materials that retain the optical properties in a wide range of external influences such as temperature, humidity, mechanical impact, pressure, ultraviolet radiation, etc.

Allowed to use MPS in high-density electronic modules in a monolithic performance, and in printed circuit boards using modern materials. Waveguide systems have wide usage possibilities – in particular, in radar complexes, devices of avionics, guidance systems of precision weapons, high-performance computers, as well as, for example, in vehicles to ensure the smooth operation of the management Board and Supervisory electronics.
