Abstract
A silicon photonic platform includes a composite substrate with a first photonic platform layer which includes a photonic platform material. A first signal layer covers the first photonic platform layer, has a top surface, and includes the photonic platform material and a first signal material. A photonic platform spectral signal is different from the first signal material spectral signal. The second photonic platform layer has a top surface, covers at least a portion of the top surface of the first signal, and includes the photonic platform material. The second photonic platform layer includes at least one ridge structure, and forms a silicon photonic platform together with the first photonic platform layer.
