Engineers at the University of California, Santa Barbara, have developed a groundbreaking chip that combines a laser and a photonic waveguide, enabling the creation of a photonic integrated circuit. The chip utilizes ultralow-loss silicon nitride waveguides and low-noise indium phosphate lasers, with a separation between the components to prevent damage during etching. The researchers successfully tested the chip's noise levels and used it to create a tunable microwave frequency generator, marking a significant step towards complex systems and networks on silicon.
