Abstract The study demonstrates high‐quality pulsed‐laser‐deposited (PLD) barium titanate (BTO) thin‐films on a magnesium oxide substrate. The frequency response of the relative permittivity (dielectric constant) and the linear electro‐opti

Electro-optic modulators are key elements in high-speed optical telecommunication links and preferably rely on materials with a linear electro-optic effect. Choosing adequate waveguide geometries is a key challenge in the design of electro-optic modu

The linear electro-optic coefficient of lithium niobate on insulator (LNOI) thin films has been characterized over a broad range of modulation frequencies from 50 MHz to 270 GHz. A coefficient of 25-30 pm/V was found.

We incorporate Fourier surfaces into silicon waveguides with vertical tapers for next generation photonic grating couplers. By combining thermal scanning-probe lithography and reactive-ion etching, we generate gratings with smoothly apodized depth pr

We demonstrate low-loss fiber-to-chip coupling via a-Si grating couplers on top of SiN waveguides for C-band TE light. The suggested simple scheme is fabrication tolerant and offers a path towards coupling efficiencies above -1 dB.

We present a plasmonic platform featuring efficient, broadband metallic fiber-to-chip couplers that directly interface plasmonic slot waveguides, such as compact and high-speed electro-optic modulators. The metallic gratings exhibit an experimental f
