Abstract

Chilas develops off-the-shelf laser sources based on hybrid integration of Photonic Integrated Chips (PICs). Combining the high optical powers of semiconducting optical amplifiers (SOAs) with low-loss wavelength tunable mirror structures on Si₃N₄ PICs results in compact and robust tunable laser sources. These extended cavity diode lasers (ECDLs) exhibit unique characteristics like wide tuning ranges (>100 nm), ultra-narrow linewidths (<1 kHz) and high output powers. Here we present up to 162.5 mW of optical output power by combining two SOAs inside a single cavity, thereby scaling the output power without the need of additional optical amplification on the output port. The presented laser operates inside the telecom C-band, but the strategy can be tailored to other wavelengths like 850 nm, 780 nm and 690 nm, where Si3N4 plays a key role. This new generation of hybrid integrated ECDLs, exhibiting high optical output powers, wide wavelength tuning ranges and ultra narrow linewidths, opens up a wide range of applications.
