Abstract

We investigated the influence of uniparabolic graded distributed Bragg reflector (DBR) using digital alloy on vertical series resistance and reflectivity of DBRs. Measured specific DBR series resistance was reduced to about 8.787${\times}$$10^{-6}$${\ohm}$ $cm^2$/period for digital alloy uniparabolic graded DBR. This was better than various graded DBRs, especially biparabolic graded DBR. Reflectivity of 42 pair uniparabolic graded DBR was found to be comparable to that of biparabolic graded DBRs.
