Résumé:
In this work we study the spatial distribution of photon modes confined in a 0D cavity and a 1D W1 on AlN-based photonic crystal membranes by spectrally resolved confocal microscopy in the ultra-violet spectral range. The analysis of the influence of the fabrication-induced disorder of the PC on the photon modes show that the cavity modes are robust with respect to disorder, whereas the 1D modes of the W1 waveguide are localized near its cut-off frequency. Modifications of the photon local density of states will be compared to simulations of weakly disordered photonic structures.
