Silicon and carbon photonics

                              Silicon photonics is the study and use of photonic systems which use silicon as an optical medium. The silicon is generally designed with sub-micrometer accuracy, into microphotonic segments. Silicon photonic gadgets can be made utilizing existing semiconductor manufacture procedures, and in light of the fact that silicon is now utilized as the substrate for most incorporated circuits, it is conceivable to make half and half gadgets in which the optical and electronic segments are coordinated onto a solitary microchip. New forms of carbon material have been obtained artificially relatively recently.
