Abstract

We design, fabricate and investigate compact Z-add-drop (ZAD) filters for long-range surface plasmon polaritons (LR-SPPs) at telecom wavelengths. The ZAD filter for LR-SPPs consists of two ridge gratings formed by periodic gold thickness modulation at the intersections of three zigzag-crossed gold stripes embedded in polymer. We investigate influence of the grating length and crossing angle on the filter characteristics and demonstrate a 10o-ZAD filter based on 80-mm-long gratings that exhibit a 15-dB dip (centered at ~1.55 mm) in transmission of the direct arm along with the corresponding ~13-nm-wide transmission peak in the drop arm.
