Dielectric laser acceleration (DLA) is based on the interaction of electrons and laser-excited near-fields at photonic structures. The resulting demonstrated acceleration gradients approaching 1 GeV/m over varying wavelengths and electron energies make this technology promising as a candidate for a small-footprint accelerator. The Accelerator on a Chip International Program (ACHIP) has been researching DLA in order to realize many of its exciting applications. Specifically, it aims to design and demonstrate a MeV electron accelerator with a shoebox-sized footprint. Here the status and outlook of this endeavor are summarized. Specifically, challenges and developments related to the necessary high brightness cathodes, transverse and longitudinal subrelativistic electron dynamics, on-chip photonics-based laser coupling and the integration of all components of the envisioned MeV accelerator are detailed.
