Abstract
Significant reflectance band broadening through arithmetic and geometric chirping of AlAs oxide/(Al,Ga)InP distributed Bragg reflector (DBR) periodicity has been demonstrated. Reflectivities >90% have been achieved for 7-pair structures over a wavelength range as large as 713 nm, and 70% reflectance was measured over a range of 1388 nm
