摘要
Apparatuses for communication or sensing are disclosed, the apparatuses comprising a substrate; a bottom cladding disposed on the substrate; a device layer disposed on the bottom cladding, wherein the device layer comprises: two substantially parallel rails extending from an input side to an output side of the device layer and configured to form a slot between the two substantially parallel rails, wherein each of the two substantially parallel rails comprises an inner edge adjacent to the slot and an outer edge opposite the slot; and one or more teeth coupled to each of the two substantially parallel rails; and a top cladding disposed onto the device layer and bottom cladding; wherein the bottom cladding, the device layer, and the top cladding are configured to support at least one optical guided mode. Other embodiments are described and claimed.
