Electro-optically tunable barium–strontium–titanate filter for the 2 μm wavelength range
We demonstrate a tunable optical bandpass filter with maximum transmittance of 67% based on a thin film substrate-transferred Ba0.5Sr0.5TiO3 (BST) layer integrated into a Fabry–Pérot cavity, designed for operation at 2 μm. The filter structure consists of a 450 nm BST film sandwiched between two dis...
