Integrated Optical Polarizer for Silicon-on-Insulator
Waveguides Using Evanescent Wave Coupling
to Gap Plasmon­Polaritons
Ivan Avrutsky
Abstract--Resonant coupling to a gap plasmon­polariton sup-
ported by a metal­dielectric nanoscale multilayer on top of a sili-
con guiding core is proposed for polarization control in silicon-on-
insulator waveguides. The device functionality relies on the unusual
dispersion properties of the gap plasmon­polaritons, whose modal
index can be significantly higher than the refractive index of the
gap layer.
Index Terms--Photonic integrated circuits, plasmonics, polariz-
ers, silicon-on-insulator.
I. INTRODUCTION
FUTURE development of integrated optics is expected
to rely on utilization of well-established complementary
metal-oxide-semiconductor (CMOS) fabrication technologies
that have been proven to facilitate high-volume manufacturing
of highly integrated electronic devices and systems. Silicon-
