Reservoir computing is a neural-inspired approach for processing temporal data. In the optical domain, it exploits the complex dynamics of photonic systems for high-speed, energy-efficient computation. Various implementations, including semiconductor lasers and integrated photonics, enable applications in pattern recognition and signal processing.

The students’ task is to provide an overview of optical reservoir computing, covering its principles, implementations, and applications.

Laser linewidth measurement is crucial for characterizing the spectral properties of lasers, particularly in applications requiring high precision. It involves determining the range of frequencies over which the laser emits coherent light. Students will perform experimental techniques to measure the linewidth. Understanding laser linewidth is essential for optimizing laser performance in communication, sensing, and metrology applications.
