Why would you go for photonic sensing?  

  1. Speed: Photonics-based sensors can operate at very high speeds, making them suitable for high-speed measurement and control applications.
  2. Sensitivity: Photonics-based sensors can be very sensitive, allowing them to detect very small changes in the physical quantity being measured.
  3. Immunity to electromagnetic interference: Photonics-based sensors are immune to electromagnetic interference, making them suitable for use in electrically noisy environments.
  4. Long distance sensing: Photonics-based sensors can be used for sensing over long distances, as light can travel through air, water, or other transparent media.
  5. Versatility: Photonics-based sensors can be used to measure a wide range of physical quantities, including temperature, pressure, humidity, strain, and displacement.
  6. Compactness: Photonics-based sensors can be made small and compact, making them suitable for use in portable or miniaturized systems.
  7. Durability: Photonics-based sensors can be made to be very durable and resistant to damage, making them suitable for use in harsh or hazardous environments.
  8. Non-invasive sensing: Photonics-based sensors can be used for non-invasive sensing, as they do not require contact with the object being measured. This makes them suitable for use in applications where contact would be undesirable or impractical.
