Abstract
We present an experimental demonstration of a polarization quasi-independent narrow-band (less than 0.8 nm) filter operating under high oblique incidence. The structure is a resonant grating with a hexagonal lattice which has been carefully designed to ensure polarization quasi-independence of the narrow-band resonance peak over a wide angular range around 60° of incidence. A good agreement between experimental results and theoretical calculations is shown.

Abstract
The photoluminescence properties of silicon nanocrystals in SiO2, prepared by low-pressure chemical vapour deposition and subsequent annealing have been studied. A comprehensive range of combinations of film compositions and annealing conditions were tested. The use of two-step annealing (a rapid annealing, followed by a conventional one) used instead of the common one-step conventional annealing, enhances emission. Annealing conditions are key to the photoluminescence and structural properties of the obtained film and have been investigated in detail. Film composition is also an important parameter, which allows tuning of the emission in a wide spectral range in the near infrared.
