Proud to have made the first hybrid integrated laser consisting of more than one InP gain sections sharing a common laser mirror. The resulting 100 mW at a pump current of twice 250 mA is the highest output power of a hybrid laser to date. Furthermore, the laser shows a low intrinsic linewidth of 320 Hz as well as a low relative intensity noise (<-160 dBc/Hz).
Tunable semiconductor lasers with a narrow linewidth have found a wide range of important applications, reaching from coherent communications, optical sensing to arising applications such as microwave photonics.
