چکیده
Abstract Ultra-compact transverse magnetic (TM)-pass polarizer based on silicon sapphire (SOS) platform is proposed and analysed. Low power consumption, high linearity speed of transmission are the major advantages SOS in different commercial applications especially mid infrared region.The suggested structure has bimetallic configuration aluminium doped zinc oxide (AZO) zirconium nitride (ZrN) to highly attenuate quasi electric (TE) mode. This due coupling between fundamental TE surface plasmon modes. However, mode can propagate with minimal losses. At 2.0 µm operating wavelength, TM-pass realizes 20.3 dB extinction ratio (ER) 0.14 insertion loss (IL) at a device length 3.0 µm. Therefore, reported design compact length, efficiency CMOS-compatibility.

Compact and integrated TM-pass waveguide polarizer.
A novel integrated TM-pass waveguide polarizer with a subwavelength-wide slot is introduced and theoretically analyzed. With a proper design of the slot, the waveguide can be used as a single polarization waveguide to guide only TM polarization modes of the light signal. With 26 microm length of this TM-pass polarizer, our computer simulations predict the insertion loss of 0.54 dB for the TM po...
متن کاملCompact hybrid TM-pass polarizer for silicon-on-insulator platform.
Hybrid waveguides consisting of a metal plane separated from a high-index medium by a low-index spacer have recently attracted a lot of interest. TM and TE modes are guided in two different layers in these structures and their properties can be controlled in different manners by changing the waveguide dimensions and material properties. We examine the effects of different parameters on the char...
متن کاملCompact Color Filter and Polarizer of Bilayer Metallic Nanowire Grating Based on Surface Plasmon Resonances
Surface plasmon resonances on bilayer aluminum nanowire gratings are studied in both theory and experiment. It is found that there are two kinds of surface plasmon on the bilayer metallic gating: longitudinal aluminum/dielectric/aluminum slit and lateral aluminum/dielectric interface waveguide mode. The surface plasmon waveguide mode resonance in the slits makes the grating act as a transverse ...
متن کاملAnalysis of TM-pass reflection mode optical polarizer using method of lines
In this work, a reflection-mode TE pass polarization filter is proposed and analyzed. Guided TE-polarized waves are highly reflected at the input end of this polarizer. On the other hand guided TM-polarized waves experience very low reflection at the same input end. The TE pass polarizer is realized by adding a corrugation in cascade with a simple three layer metal-clad optical waveguide. The m...
