All-optical processing is a hot research and X5043P datasheet and development communication, speed, power and X5043P price and cost is critical. Is the key to all-optical processing of nonlinear optical waveguide with high and X5043P suppliers and ultra high-speed performance. Karlsruhe University, Germany, Belgium, Interuniversity Microelectronics Research Center, Lehigh University and other research institutions, the U.S. researchers used silicon-based devices to achieve high-speed communications all-optical signal processing, transmission rate of 100 Gbit / s.
Researchers by deep ultraviolet lithography, the standard CMOS process and organic molecular beam deposition technology combine to create an innovative type of optical waveguide structures. This is called a silicon - organic hybrid materials (silicon-organichybrid, SOH) form of the waveguide, the all-optical signal processing, paving the way (do not bother to convert between photons and electrons), is to meet the rapid growth of the future needs of global communications solutions of the most promising one.
Researchers mature CMOS process to manufacture waveguides, organic molecular beam deposition technique used in the waveguide is covered with organic molecules, these organic molecules make SOH nonlinear waveguide with a step, and not introduced larger loss. SOH up to 4 mm of the 1.55 μm communications band waveguide, the nonlinear coefficient of about 105 (Wkm) -1, the theoretical value for the first time the test has been verified. In such a waveguide, through four-wave mixing will 170.8Gbit / s all-optical demultiplexing into a 42.7 Gbit / s. This is by far the photon optical signal processing speed world record, the experiment confirmed the SOH waveguide can be applied to all optical broadband communication signal processing is feasible.
This SOH silicon waveguide beyond some inherent limitations. Silicon-based technology is considered very suitable for manufacturing a variety of passive linear optical devices. However, due to nonlinear effects in silicon harmful, ultra high-speed development of active silicon-based features, such as all-optical switch, is still a major challenge. So far, the silicon waveguide signal transmission rate limit is 40 Gbit / s. SOH waveguide beyond this limit, the rate exceeds 100 Gbit / s. Related study, published in "Nature - Photonics" (Nature Photonics) on (title of the article: All-optical high-speed signal processing with silicon-organic hybrid slot waveguides).
