Abstract
A component comprising a stacked interleaved film structure that includes a plurality of layers inert to light. Alternating layers are either doped with a reverse saturable absorber (RSA) material or the RSA material is located between the adjacent inert layers. In some embodiments, the inert alternating layers have different refractive indices. A data storage device and methods of manufacture are also disclosed.
Claims34
A component comprising:
- a stacked film structure comprising a plurality of layers inert to light having a first refractive index interleaved with a plurality of layers inert to light having a second refractive index, wherein in the first refractive index is different than the second refractive index;
- and
- a plurality of layers comprising a reverse saturable absorber (RSA) material, wherein each of the plurality of layers is located between one of the plurality of layers inert to light having the first refractive index and one of the plurality of layers inert to light having the second refractive index.
A method of manufacture comprising:
- providing a plurality of layers inert to light having a first refractive index;
- providing a plurality of layers inert to light having a second refractive index, wherein the first refractive index is different than the second refractive index;
- applying a reverse saturable absorber (RSA) material to at least one of the layer inert to light having the first refractive index and the layer inert to light having the second refractive index;
- and
- adhering the plurality of layers inert to light having the first refractive index to the plurality of layers inert to light having the second refractive index, so that the plurality of layers inert to light having the first refractive index and the plurality of layers inert to light having the second refractive index are interleaved, thereby forming a component having the RSA material located between the layer inert to light having the first refractive index and the layer inert to light having the second refractive index.
