BPM - Figure 1 This is Fig.2 of Reference 1, drawn upside down. This waveguide is a ‘Substrate-Removed’ design, so the cladding is BCB, a polymer used to glue the waveguide to another substrate, not shown. This mounting exposes the AlGaAs cladding layer to air, and the Backside electrode is evaporated there. All lengths are in microns.

Electro-Optic Modulator

  This lesson shows how to make a 3D simulation in a material modified by the linear electro-optic effect (Pockels Effect). The waveguide design of Reference [1] is shown in Figure 1 below. In this lesson, this waveguide is created, a …
