At the Technical University of Munich has been claiming the naolaser that will be thousand times more thinner than the human hair. This nano wire laser will be grown on the chips of silicon. That will be making the device to be more high performing in the field of photonic components that will make it cost effective.
This process of miniaturisation of the electronic device is now limiting the physical quantities  and now the transistors are just few nanometer long in size. By depositing nanowires that are freestanding with a footprint of a few square nanometers, the scientists could preclude the emergence of defects in the GaAs material.
