Abstract

See full text

A polymer modulator including a waveguide core defined over an insulating layer and having a first passive region including a light input, a second passive region including a light output, and an active region optically coupling the passive regions into a continuous waveguide core between the input and output. The waveguide core in the first and second passive regions including one of sol-gel and SiO2 surrounded by cladding including one of sol-gel and SiO2. The cladding in the passive regions having a first refractive index, the waveguide core in both regions having a second refractive index at least 0.01 higher than the first refractive index. The waveguide core in the active region including sol-gel, a cladding layer of sol-gel positioned between the insulating layer and the waveguide core, the refractive index of the waveguide core is at least 0.01 higher than the refractive index of the cladding layer.
