Distributed Bragg Reflector (DBR) Laser Diodes
Introduction to DRB lasers Distributed Bragg Reflector (DBR) laser diodes are a class of single-frequency monolithic semiconductor lasers. Monolithic semiconductor lasers in general are small in size, mechanically robust, and have good power conversion efficiency. They also provide opportunities for hybrid integration with photonic integrated circuits (PICs). This application note provides an overview of DBR lasers, their principles of operation, their modal behavior, and their diverse applications. Principles of DBR Laser Operation A DBR laser is a semiconductor laser with one or several quantum wells Continue reading →
