Types of Optical Switches

1. Mechanical Switches: Use moving optical elements to redirect light paths, suitable for low-speed or high-reliability applications .
2. MEMS (Micro-Electro-Mechanical Systems) Switches: Utilize tiny mirrors controlled by electrostatic forces to switch optical signals rapidly, ideal for multi-channel and compact systems .
3. Bending or Thermal Switches: Alter the refractive index of waveguides using localized heating to redirect light, often used in integrated photonics .
4. All-Optical Switches: Operate entirely in the optical domain without converting signals to electrical form, reducing latency and power consumption, and are increasingly used in data centers and 5G/6G networks .
