The integration of nanojoule, femtosecond pulse lasers onto a photonic chip represents a leap in miniaturization and efficiency for ultrafast optics. For crypto, the long-term relevance lies in potential applications for high-bandwidth data centers, quantum-resistant cryptography, and energy-efficient mining hardware—areas where photonic computing could reduce power consumption and latency. However, commercialization is years away.
