In this contribution we study how a planar photonic crystal waveguide (PhCW), created by introducing a line defect in the photonic crystal, can modify the projected local density of states (LDOS) for a dipole emitter. We use the COMSOL Multiphysics® RF Module to carry out eigenvalue calculations studies on PhCW. When the dipole is in resonance with the waveguide mode, the enhancement Fp of emission with respect to the emitter in the homogenous medium can be calculated for different dipole orientations. In conclusion, we studied the LDOS in a photonic crystal waveguide for different positions of the emitter at different frequencies. These results prove the existence of efficient and position insensitive coupling between embedded emitters and PhCW modes.
