We demonstrate the first on-chip laser frequency comb based on hybrid integration with low-loss Si3N4 waveguide circuits. The laser comprises an InP diode amplifier of which a small fraction is reverse biased for passive locking, while a Si3N4 feedba

Gain around 981 nm in Yb-doped potassium-double-tungstate channel waveguides increases linearly with dopant concentration up to ~50% Yb. A 55-nm gain bandwidth obtains in all waveguides, with at least 150 dB/cm for 47.5% Yb concentration.
