Yes—finally! Generation of intense ultrafast pulses directly on chip brings a new capability to photonic integrated circuits (PICs) and enables integration of more functionalities, such as monolithic piezo actuators.
Scientists have finally packed a laboratory-class ultrafast laser onto a tiny photonic chip. Ultrafast lasers generate bursts of light that last only a few hundred femtoseconds, each one just a quadrillionth of a second long. These extremely short pulses are used in a wide range of technologies, including precision manufacturing, eye surgery, and optical frequency [...]
