Microphotonics is an emerging branch of optics . Laboratory work recently suggest that speed of light can be decreased, but not increased. So there must be some technology behind to increase the speed of light. That would help us control the properties of light like any matter.Certainly can look forward for a faster High-definition travel in the future.Can improve-make faster the current speed of networking also using quantum teleportation or Optical Networking if the speed of light is increased.
