Abstract :
Approximating a distributed Bragg reflector (DBR) of intracavity-contacted VCSELs by using an electrically-averaged single layer leads to unrealistic results about current crowding effect. Keeping one or two pairs of constituting layers of DBRs in contact with the nearby N- and P-contact layers from being approximated leads to more realistic results
