Two-dimensional photonic crystal slab waveguide

A method for fabricating a two-dimensional photonic crystal slab apparatus, comprising:

• providing a dielectric slab supported on a first substrate;
• forming a two-dimensional array of dielectric structures in said dielectric slab to form a two-dimensional photonic crystal slab;
• and
• forming first and second cladding layers on first and second surfaces of said photonic crystal slab, said first and second cladding layers each including a metallic cladding layer.

A method for fabricating a two-dimensional photonic crystal slab apparatus that includes first and second metallic cladding layers, comprising:

• providing a dielectric slab supported on a first substrate;
• forming a two-dimensional array of dielectric structures in said dielectric slab by an etch process to form a two-dimensional photonic crystal slab;
• depositing a first metallic cladding layer on a first surface of said two-dimensional array of dielectric structures;
• mounting a second substrate to said first metallic cladding layer;
• removing said first substrate;
• and
• depositing a second metallic cladding layer on a second surface of said two-dimensional array of dielectric structures.
