High Efficiency Volume Diffractive Elements in Photo-Thermo-Refractive Glass

Diffractive broadband coupling into high-Q resonant cavities.

Optical resonators with high-quality factors (Q-factor) constitute the main building block for many photonic devices capitalizing on light-matter interactions, ranging from light emitters to biochemical sensors. While a high Q-factor enhances light-matter interactions, it also limits the device operation bandwidth. Here we propose and numerically analyze a generic coupling scheme to overcome th...

High-Efficiency Resonant Cavity Quadrupole Moment Monitor

Measurement of the beam quadrupole moment at several locations can be used to reconstruct the beam envelope and emittance parameters. The measurements can be performed in a non-intercepting way using a set of quadrupole-mode cavities. We present a cavity design with an optimized quadrupole moment shunt impedance. The cavity properties can be characterized using a wire test method to insure symm...

High voltage gain DC-DC resonant converter

In this paper, a DC-DC resonant converter with high voltage gain and small size is studied. To reduce the size and weight of this converter, the operating frequency should be as high as possible. In this research, the frequency changes from 120 to 200 kHz. Due to the high operating frequency, it is necessary to reduce the switching losses using soft switching methods. Resonant converters are su...
