ABSTRACT
The infiltration of three-dimensional opal structures has been investigated by atomic layer deposition. Demonstrations using ZnS:Mn show that filling fractions >95% can be achieved and that the infiltrated material is of high-quality crystalline material as assessed by photoluminescence measurements. These results demonstrate a flexible and practical pathway to attaining high-performance photonic crystal structures and optical microcavities. © 2003 American Institute of Physics.

    Silica opals are used as templates where CdS is infiltrated with the aim to build inverse structures with enhanced photonic band gap properties. A control on the degree of infiltration, from 0% to 100%, is attained. The band gap at L is studied finding that the width decreases and then recovers...
