 Solution-based distributed Bragg reflector, DBR, a technology has made significant progress over the past few years, but still faces some limitations before being ready for commercial use. The main obstacle is the difficulty of producing high refractive index, HRIF films, which are needed to achieve high reflectance from a small number of layers. Materials and coating processes have been developed to address this issue, however, and recent advancements have brought solution-based DBRs close to the level of physical-slash-chemical vapor deposition, PVD. Additionally, DBR research has expanded beyond photonic applications, making it easier for researchers with different backgrounds to access the necessary information.
