... expected of the Polarimetric Anomaly Parameter, (Pmax)aA, proposed by Shkuratov and others. In the remainder of this paper, we refer to this shift in the Umov plot as a Polarisation Anomaly to distinguish it from the Polarimetric Anomaly Parameter, and we discuss the relationship between these two q ...

Deposition and Characterization of Dielectric Distributed Bragg

... To improve the performance of VCSELs, mirrors with less optical loss can be used. VCSELs require mirrors with > 99 % reflectance, and Distributed Bragg Reflectors (DBRs) are used to achieve this. Today, epitaxially-grown semiconductor DBRs are used, however these have low refractive index contrast, ...
