- Abstract
A design for omnidirectional asymmetrical high reflectors for optical telecommunication wavelengths is described. Asymmetry was introduced by applying a power law, so that the coordinatesyof the transformed object were determined through the coordinatesxof the quarter-wave stack air/H(LH)15/air in accordance with the following ruley=x1 +k. Herekis the coefficient defining the asymmetry degree. It is shown that a high-reflection band at any incident angle for both polarizations, i.e., an omnidirectional high reflection band of 0.74m for optical telecommunication wavelengths 0.85 and 1.3m is found for the transformed system: air/Te(SiO2/Te)15/air corresponding to the optimizedkvalue 0.24.
