Semiconductors like gallium arsenide or indium phosphide convert electrical signals into light (photons) using Laser Diodes or LEDs . Photonics - Optical Electronics in Modern Comm.

Light pulses travel through Optical Fibers , which use thin glass cores to guide signals over thousands of miles. Introduction to Photonics: Principles and the Most Recent

In the late 20th century, modern communication underwent a quiet revolution—shifting from the movement of in copper wires to the movement of photons (particles of light) through glass. This field, known as Photonics or Optical Electronics , is now the backbone of the internet, global telecommunications, and advanced data centers.
