Abstract
A method for forming an embedded mirror structure is disclosed. The method includes preparing a structure that has a substrate and a waveguide layer on the substrate. The waveguide layer includes a core. Also, the waveguide has a top surface and a cavity side surface that defines a cavity opened at the top surface and aligned to the core. The method further includes coating metal particles on the cavity side surface inside the cavity of the waveguide layer to form a metal particle film on the cavity side surface.
