Abstract

We represent a high speed evanescently coupled waveguide UTC-PD. It is shown that a layer of polymer layer under the electrical pads can enlarge the response bandwidth of a UTC-PD greatly. The effects of the polymer layer are also studied with numerical simulations, which show the same trend.
