A Diffractive Optical Element with Gradient Refractive Index Micro-Structure Imprinted in Chalcohalide Glasses

Abstract

Abstract: A diffractive optical element (DOE) with a gradient refractive index (GRIN) micro-structure which was imprinted in the chalcohalide glass covering a range of visible to mid-infrared wavelengths, was prepared by an efficient and inexpensive micro-thermal poling process. The influence laws of polarization parameter (polarization voltage U) of micro-thermal poling on the morphology, micro-structure, diffraction effect and diffractive optical element of chalcohalide glass were investigated. The effective imprinting of GRIN micro-structure on chalcohalide glass was found to be in a range of 0.75 kV to 1.00 kV for U. The depths of surface morphology and the number of the diffraction orders increase with the increment of U, but the micro-thermal poling has little effect on optical transmission and doesn’t affect the practical applications. After the micro-thermal poling process, GRIN micro-structure with a period length of 25 μm and a maximum phase difference of up to 0.60λ (λ=632.8 nm) are observed on the surface of the chalcohalide glass. The main sources of its diffraction performance are the migration of K⁺ on the subsurface near the anode side and the periodic GRIN micro-structure formed by the rearrangement of glass structure.

Key words: micro-thermal poling, diffractive optical element, gradient refractive index, chalcohalide glass, micro-structure, morphology
