+18 dBm High-Power Tunable Laser Modules for Digital Coherent Optical Communication Systems

摘要

With the rapid increase in communication traffic, digital coherent communication technology has spread, particularly for trunk networks. For the application of the technology to metropolitan area networks and data center interconnection, compact and high-power light sources that enable high-density mounting in communication units are required. We have developed a microintegrable tunable laser assembly (Micro-ITLA) using a tunable distributed amplification chirped sampled grating distributed reflector (TDA-CSG-DR) laser that achieves the industry's highest output power of +18 dBm.
