   Well not necessarily. You can synthesise modulated  RF with enough   
   square waves.   
      
   Juts run it through a filter afterwards.

   Yes. But optical lasers are a lot higher.   
      
   "Optical laser frequencies represent the oscillation speed of   
   electromagnetic waves in the visible, infrared, or ultraviolet spectrum,   
   generally falling between 400 THz and 700 THz for visible light, with   
   higher frequencies for UV and lower for infrared."   
      
   Laser diodes have been around a while...
