Abstract: There is provided an integrated laser. The integrated laser includes a semiconductor waveguide having a first section, a second section and a third section. The integrated laser further includes an active region formed on the third section of the semiconductor waveguide, the active region configured for generating light, and a coupler formed on the second section of the semiconductor waveguide, the coupler configured for coupling said light between the semiconductor waveguide and the active region. In particular, the first section comprises a multi-branch splitter having a ring structure formed between two branches of the multi-branch splitter for emission wavelength control of the integrated laser. Preferably, the multi-branch splitter is a Y-branch splitter and the ring structure is formed in a space between two branches of the Y-branch splitter. There is also provided a method of fabrication thereof, an integrated tunable laser and an integrated tunable laser system.
