Fixed field phase shifters for a multipass recirculating superconducting proton linac

Physical Review Accelerators and Beams, 2021
The multi-pass recirculating proton linac can significantly improve the usage efficiency of rf superconducting cavities by accelerating the proton beam through the same cavity multiple times. However, in order to achieve acceleration for different energy

All‐fibre phase shifter based on tapered fibre coated with MoWS2‐rGO

IET Optoelectronics, 2021
In this work, an all‐fibre phase shifter using tapered fibre coated with molybdenum tungsten disulfide ‐ reduced graphene oxide (MoWS2‐rGO) is demonstrated. The large evanescent field of tapered fibre allows MoWS2‐rGO to absorb injected light from a 1400‐

Proposing a Modified Switchable Schiffman Structure to Implement a Wideband and Low-Loss 4-bit Digital Phase Shifter

IEEE Access
This paper proposes a modified Schiffman structure to implement a wideband, low-loss 4-bit digital phase shifter. Here, low-cost positive intrinsic negative (PIN) diodes are used for electronically controlling the phase states of the phase shifter.

A TCAD study on the effect of process parameters on silicon optical phase shifter performance

Frontiers in Physics, 2023
On-chip integrated optical phase shifters are an important part of optical phase modulators. The performance of such modulators relies heavily on the phase shifter performance, which in turn depends on multiple process parameters.
