Carlos M. S. Vicente et al. (see pp. 280–282 ) have fabricated high‐rejection optical filters based on first‐order Bragg gratings which were inscribed in channel waveguides through UV‐laser writing in transparent, low surface roughness (<0.1 nm), and low‐loss (1.5 ± 0.2 dB cm –1 , 532 nm) thin films of organic–inorganic hybrids with controlled refractive index values stable under aging. The high‐rejection figure of merit (∼24 dB) of these optical filters is the best value found until now for organic–inorganic hybrids, reinforcing the potential of sol–gel technology in the fabrication of cost‐effective integrated optics devices for the next generation of optical networks.
