Abstract
An optical module that provides a feedthrough to carry an electrical signal output from and/or provided to a semiconductor optical device is disclosed. The feedthrough has a signal pad that carries the electrical signal thereon and at least two ground pads sandwiching the signal pad therebetween. The feedthrough further provides a cavity provided under the signal pad and spaces each between the signal pad and the ground pads.
