Surface plasmon polariton based modulators and switches operating at telecom wavelengths
T Nikolajsen, K Leosson, SI Bozhevolnyi - Applied Physics Letters, 2004 - pubs.aip.org
We report design, fabrication, and characterization of thermo-optic Mach–Zender
interferometric modulators and directional-coupler switches whose operation utilizes the
long-range surface-plasmon-polariton waveguiding along 15-nm-thin and 8-μm-wide gold
stripes embedded in polymer and heated by electrical signal currents. The devices are
characterized at the light wavelength of 1.55 μm, featuring low driving powers (< 10 mW for
modulators and< 100 mW for switches), high extinction ratios (> 30 dB), moderate response …
