We study slanted coupled nanocavity array formed by two-point-defect (L2) nanocavities with loaded Q factor of 0.6 million, which period is shorter than previous reports. We report experimentally observed coupled cavity modes formed by fundamental and high-order cavity modes and discuss the potential of the coupled nanocavities as a broadband nano-waveguide.
