Abstract: Femtosecond laser pulses enable the synthesis of light across the electromagnetic spectrum and provide access to ultrafast phenomena in physics, biology, and chemistry. Chip-integration of femtosecond technology could revolutionize applications such as point-of-care diagnostics, bio-medical imaging, portable chemical sensing, or autonomous navigation. However, current sources lack the required power, and the on-chip amplification of femtosecond pulses is an unresolved challenge. Here, addressing this challenge, we report >50-fold amplification of 1~GHz repetition-rate chirped femtosecond pulses in a CMOS-compatible photonic chip to 800 W peak power with 116 fs pulse duration. Nonlinear effects, usually a hallmark of integrated photonics but prohibitive to pulse amplification are mitigated through all-normal dispersion, large mode-area rare-earth-doped gain waveguides. These results offer a pathway to chip-integrated femtosecond technology with power-levels characteristic of table-top sources.
