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.
