Abstract

We present the focused-ion-beam fabrication of slots in existing silicon waveguides and racetrack resonators. The etch process was conducted with iodine enhancement and an alumina hard mask. We demonstrate a propagation loss of 100 dB/cm for slot waveguides and a Q value of 850 for slot racetrack resonators with bend radius of 6 $mu {hbox{m}}$.
