Substrate-transferred stacked optical coatings

A method for manufacturing a hybrid optical mirror assembly, comprising:

• a) providing a first optical coating having multiple layers of alternating high and low refractive indices of crystalline materials on a first host substrate via an epitaxial growth technique;
• b) providing a second optical coating having multiple layers of alternating high and low refractive indices of dielectric materials on the first optical coating via a physical vapor deposition (PVD) technique;
• c) directly bonding the second optical coating to a second host substrate;
• and
• d) removing the first host substrate;
• wherein the multiple layers of alternating high and low refractive indices of crystalline materials comprise GaAs/AlGaAs layers, and the multiple layers of alternating high and low refractive indices of dielectric materials comprise Si/SiO2 layers or Ge/ZnS layers.
