"High power photodiode" was invented by Jason Ackert (Ottawa), Chengkun Chen (Ottawa) and Marcel G. Boudreau (Ottawa).

According to the abstract* released by the U.S. Patent & Trademark Office: "In some implementations, a photodiode includes a waveguide layer of a first semiconductor material. The photodiode may include a first ion-implantation region, in the first semiconductor material, that is doped to exhibit a first conductivity type. The photodiode may include a mesa, of a second semiconductor material, on the waveguide layer. The first ion-implantation region may be set bac...
