Micro-electromechanical systems (MEMS) have the potential to provide low-power phase shifting in silicon photonics, but techniques for designing low-loss devices are necessary for adoption of the technology. Based on coupled mode theory (CMT), we der

We report a silicon-photonics process for MEMS-tunable phase shifters that leverages orthogonal optical modes. A phase shifter with -0.63dB insertion loss and π phase shift and a preliminary tunable directional coupler are demonstrated.

We present two compact ultrafast electron injector designs with integrated focusing that provide high peak brightness of up to $1.9*10^{12} A/m^2Sr^2$ with 10s of electrons per laser pulse using silicon carbide electrodes and silicon nanotip emitters

We reveal quantum features in laser acceleration arising from the underlying wave nature of the accelerated electron, and we present the first accelerator on-chip operated inside a transmission electron microscope.
