Context: Researchers from Tampere University (Finland) and Université Marie et Louis Pasteur (France) found that intense light pulses in optical fibres can perform AI tasks faster and with lower energy use than conventional computers.
About Light-based computers (Optical computers):
• What It Is?
• Light-based computers, or optical computers, use photons (light particles) instead of electrons to process information. They promise ultra-fast, energy-efficient, and high-bandwidth computing – ideal for AI and big data tasks.

• They promise ultra-fast, energy-efficient, and high-bandwidth computing – ideal for AI and big data tasks.
• Discovered by: Recent breakthrough credited to Tampere University and Université Marie et Louis Pasteur teams who demonstrated AI image recognition using light through glass fibres.
• How It Works:
• Step 1: Convert data (like an image) into a light pulse. Step 2: Send this pulse through an optical fibre, where light behaves in a unique way (non-linear response). Step 3: The light’s changes (colour spectrum or “fingerprint”) carry the transformed data. Step 4: This transformed light data is decoded to produce the result — e.g., identify a number in an image.

• Key Characteristics:
• Speed: Light travels faster than electricity — enabling near-instant calculations. Efficiency: Generates less heat, saving power compared to silicon chips. Parallel Processing: Can handle multiple data streams at once (different light colours = different signals). Accuracy: Achieved over 91–93% image recognition success in experiments. Scalability: Works best when fibre length and light strength are optimised.
