AB  - Emerging accelerator concepts increasingly rely on the combination of high frequency electromagnetic radiation with electron beams, enabling longitudinal phase space manipulation which supports a variety of advanced applications.  The handshake between electron beams and radiation is conventionally provided by magnetic undulators which unfortunately require a balance between the electron beam energy, undulator parameters and laser wavelength.  Here we propose a novel scheme using laser-driven large-core anti-resonant optical fibers to manipulate electron beams. We explore two general cases using TM<sub>01</sub> and HE<sub>11</sub> modes. In the former, we show that large energy modulations <i>O</i>(100 keV) can be achieved while maintaining the overall electron beam quality.  Further, we show that by using larger field strengths <i>O</i>(100 MV/m) the resulting transverse forces can be exploited with beam matching conditions to filter arbitrary phases from the modulated electron bunch, leading to the production of  ≈ 100 attosecond FWHM microbunches. Finally, we also investigate the application of the transverse dipole HE<sub>11</sub> mode and find it suitable for supporting time resolved electron beam measurements with sub-attosecond resolution.  We expect the findings to be widely appealing to high-charge pump-probe experiments, metrology, and accelerator science.
