Abstract :
Epitaxial AlGaAs/AlAs DBR mirror stacks have been investigated to determine the maximum reflectivity achievable for 550 nm wavelength. A maximum reflectivity of greater than 90% has been achieved despite the optical loss in the AlGaAs, and a 70% peak reflectivity can be achieved with as few as five mirror periods.
