abstract = {Several subwavelength grating mirrors have been designed for
VCSEL application in mid-infrared wavelength range (\λ = 2.3 µm).
These mirrors are automatically optimized thanks to a global
algorithm which maximizes a specially defined quality factor for
VCSEL top mirrors. Three different designs based on Si/SiO2,
AlGaSb/GaSb and GaAs/AlOx are simulated and exhibit bandwidth as
large as 206 nm. Also, the bandwidth is polarisation selective
with a TM reflection coefficient higher than 99.9 % while TE
coefficient is kept below 90 %. These reflectors present several
fabrication solutions with a trade off between technological
limitations, tolerances in regard to the fabrication error and
mirror quality.}
