This 15-minute talk by Professor Richard Penty from Cambridge University explores the development of large port count optical switches using photonic integrated circuits. Discover the various fabrication approaches in generic foundries, including both indium phosphide and silicon photonic methods. Learn about recent advances in heterogeneous integration techniques such as micro-transfer printing, direct epitaxial growth, and additive manufacturing processes like two-photon polymerization. Understand how these innovative integration methods can significantly impact the future development and implementation of photonic switches in computing and networking applications.
