Distributed Bragg Reflectors for GaN-Based Vertical-Cavity Surface-Emitting Lasers
Applied Sciences, 2019 A distributed Bragg reflector (DBR) is a key building block in the formation of semiconductor microcavities and vertical cavity surface emitting lasers (VCSELs). The success in epitaxial GaAs DBR mirrors paved the way for the ubiquitous deployment of III-

Feedback Sensitivity of DBR-Type Laser Diodes
IEEE Photonics Journal, 2021 It is shown theoretically that the feedback sensitivity of Distributed Bragg Reflector laser diodes with low-loss Bragg section decreases with the length of the Bragg section and also can be decreased by detuning from the Bragg peak.

Modelocked distributed Bragg reflector laser
Electronics Letters, 1999 The fabrication and performance of a modelocked distributed Bragg reflector laser is described. The laser has a threshold current of 60 mA and differential efficiency of 0.05 mW/mA when coupled into a singlemode fibre. Modelocked pulses with 7 ps pulsewidth, with a time-bandwidth (/spl Delta/t/spl Delta//spl nu/) product of /spl sim/0.7, at /spl sim/5 ...

Porous AlGaN-Based Ultraviolet Distributed Bragg Reflectors [PDF]
Materials, 2018 Utilising dislocation-related vertical etching channels in gallium nitride, we have previously demonstrated a simple electrochemical etching (ECE) process that can create layered porous GaN structures to form distributed Bragg reflectors for visible light at wafer scale. Here, we apply the same ECE process to realise AlGaN-based ultraviolet distributed
