 AbstractThe paper presents results of a study of slow light excitation and power enhancement on a waveguide with a grated section. The 500 periods grating was successfully fabricated by combining a conventional mask lithography step with laser interference lithography. The grating was characterized using both an end-fire and an infrared camera setup to measure respectively the transmission and to map and quantify the power scattered out of the grating. We report an estimated factor for the group velocity slowdown in a finite periodic structure of about 10 times, corresponding to a speed of 0.1c.
