The present invention proposes an optical band-pass filter with blocked sidebands. The filter comprises a photonic crystal structure based on macroporous silicon having a series of pores defined in the structure. The photonic crystal structure includes a resonator block (BR), comprising at least two periodicity groups (GR, GR) between which there is a resonant cavity (CR), wherein the resonant cavity (CR) is adapted to provide a resonance peak in the center of a non-transmitting frequency band of the resonator block (BR); and at least one of a high-pass block (BPA), adapted to block wavelengths below said non-transmitting frequency band; or a low-pass block (BPB), adapted to block wavelengths above said non-transmitting frequency band.
