f of principle electrons laser acceleration experiments, car- ried out by several groups, have demonstrated accelerating gradients larger than 200 MeV/m. However, the adopted configurations (free space coupled gratings, dual pillar, phase reset devices) cannot be easily scaled in length, because they require a transversely incident laser light, impinging laterally along the whole in- teraction dielectric structure. In this paper, extended interaction structures with collinear propagation of the accelerating electromagnetic field and the particles to be accelerated are described: both 2D and 3D photonic-crystals-based structures and slot hollow-core waveguides are compared in terms of accelerating gradient and characteristic interaction impedance, a fundamental quality parameter for Dielectric Laser Accelerators (DLAs).
