The future looks bright for photonic integrated circuits (PICs) as they look destined for use in quantum computing and deep learning technologies. As PICs carry light signals rather than electrical signals, accurate control of their refractive properties is essential. Traditional techniques for programming photonic devices rely on exposure to light and heat. However, this leads to high power consumption and requires complex control circuits.
