Non-uniform Birefringence in Highly-reflective Substrate-Transferred GaAs/Al${}_{0.92}$Ga${}_{0.08}$As Coatings at 1064 nm

Andri M. Gretarsson, Ambroise L. M. Juston, Benjamin Nicolai +8

Using a custom-built scanning system, we generated maps of birefringence on reflection at $\hat{I}»=1064$~nm from single-crystal GaAs/Al${}_{0.92}$Ga${}_{0.08}$As Bragg reflectors (hencefort…
