We investigate the optical properties of the dipole-like modes of an H1 nano-cavity consisting of a single missing airhole imbedded into a triangular two-dimensional silicon nitride (Si3N4) based photonic crystal coated with a red-fluorescent molecular dye. We modify the size and position of the first six neighboring airholes around the nano-cavity and demonstrate that this allows control over the energy and separation of two dipole-like optical modes (Mx and My). This allows us to produce either linearly polarized optical modes or an unpolarized optical mode composed of degenerate modes having orthogonal polarization. We confirm our findings using three-dimensional finite difference time domain calculations.
