Abstract Tunable lasers with high SMSRs are cost-effective solutions to replace multiple DFB lasers as the light source for WDM systems. Interferometer-based lasers, such as C3 and Y-lasers, have advantages over grating- and ring-resonator-based lasers in terms of cost and fabrication complexities; however, a large optical path difference between the two arms is required for high SMSRs but it defeats the Vernier effect and reduces the wavelength tuning range. In our proposed three-branch MMI laser, two tuning arms with similar lengths ensure a wide tuning range, and an additional long arm provides extra optical interferences and increases the SMSR. In this project, our designed laser can be optimized to be single-mode across the entire C-band, and the use of a self-imaging MMI avoids additional losses that would potentially increase the threshold. Based on our simulation, the laser wavelength of the device can be electrically tuned over 30 nm with a 100-GHz ITU channel spacing. It is expected that, upon the completion of the project, the developed tunable laser can serve as a low-cost solution for datacom and telecom applications.
