Monolithic tunable lasers for low cost DWDM networks – Presented by Jian-Jun He, Zhejiang University

Monolithic tunable lasers for low cost DWDM networks – Presented by Jian-Jun He, Zhejiang University, Lightip Technologies Co. Ltd. at the 19th edition European Conference on Integrated Optics, which takes place on 3 – 5 April 2017 at Eindhoven University of Technology, Blauwe Zaal in Eindhoven, The Netherlands.

Low-cost tunable lasers are key enablers for next-generation dense wavelength division multiplexing (DWDM) based access and metro networks. We review the development of a simple and compact monolithic tunable laser based on half-wave-coupled V-cavity. By using a specially designed half-wave coupler between two Fabry-Perot lasers of slightly different lengths, a widely-tunable single-mode laser with high side mode suppression ratio is achieved without requiring complex gratings. Wavelength tuning up to 50 channels at 100 GHz spacing has been achieved with a chip size of only 0.5mm´0.3mm. The latest results on high-speed modulation, fast wavelength tuning, and transceiver modules will be presented.
