Abstract

Hybrid integrated planar photonics provides silica waveguides for transport and polymer or hybrid silica/polymer waveguides for refractive-based active functions within a single integrated photonic circuit. Functions include modulation, attenuation, switching, filtering, and exceptionally low-loss transport. When the active and passive optical elements are integrated onto the same substrates, the resulting composite devices can exhibit strong functional response with little total optical loss as compared to known methods.
