Slot waveguide fabrication

A slot-waveguide consists of two strips or slabs of high-refractive-index (n) materials separated by a subwavelength-scale low-refractive-index (n) slot region and surrounded by low.Each structure has advantages and disadvantages related to fabrication: the vertical slot enables slot fabrication.
