Paper Abstract

We report the experimental and theoretical results for high reflectivity (>99% at 850 nm) AlAs/AlGaAs distributed Bragg reflectors (DBR) for vertical cavity surface emitting semiconductor lasers (VCSEL). It is investigated that up to ± 10% deviations in thickness distribution of DBR layers negligibly affects the reflected bandwidth if the distribution is random. However, ascending/ descending order in thickness distribution beyond ±5% results in rapid shrinking of the reflected bandwidth with >99% reflectivity.
