  Color centers in wide-bandgap semiconductors are a promising class of
solid-state quantum light source, many of which operate at room temperature. We
examine a family of color centers in aluminum nitride, which emits close to 620
nm. We present a technique to rapidly map an ensemble of these single photon
emitters, identifying all emitters, not just those with absorption dipole
parallel to the laser polarization. We demonstrate a fast technique to
determine their absorption polarization orientation in the c-plane, finding
they are uniformly distributed in orientation, in contrast to many other
emitters in crystalline materials.
