TL;DR: Sub-wavelength structures with a subwavelength pitch have been known since Hertz conducted his first experiments on the polarization of electromagnetic waves as discussed by the authors, and their applications include anti-reflective coatings, polarization rotators, high-efficiency fiber-chip cou-plers, spectrometers, highreflectivity mirrors, athermal waveg- uides, multimode interference couplers.

Mode conversion in tapered submicron silicon ridge optical waveguides
TL;DR: It is shown that this kind of mode conversion could be depressed by carefully choosing the tapers parameters (like the taper width, the etching depth, etc), which is important for the applications when low-loss propagation for the TM fundamental mode is needed.
