The study demonstrates reduced light emission angles in resonant cavity light-emitting diodes, suggesting improved performance through multilayer DBRs and microlenses.
The paper investigates methods to reduce the light emission divergence angle in resonant cavity light-emitting diodes (RCLEDs) using a multilayer distributed Bragg reflector (DBR) and a microlens (ML) structure. By integrating staggered multiple quantum wells (SMQWs) and nanoporous DBRs, the study explores the effects of adjusting DBR cycles and adding microlenses. The results show that these approaches significantly reduce the emission angle, enhancing wavelength stability and device performance. This optimization is valuable for applications requiring highly directional light, such as optical communications, micro-LED displays, and augmented reality (AR).
