title = "Narrow linewidth brillouin laser based on chalcogenide chip",
abstract = "We demonstrate a narrow linewidth Brillouin ring-cavity laser based on chalcogenide photonic chip. The gain medium is a 7 cm-long As2S 3 waveguide with a cross-section of 4μm x 850nm and the Brillouin gain coefficient of 0.7 10-9 m/W. The waveguides are equipped with vertical tapers so that the coupling loss is reduced. The lasing threshold is approximately PL=360 mW, almost 5 times lower than the calculated single-pass threshold P0=1.73 W in the same waveguide. The slope efficiency is found to be 30% and the linewidth of 100 kHz is measured using a self-heterodyne method.",
