In this paper, we report on the photonic device fabrication inside silica glasses by loosely focused fs laser under the conditions of incident pulsewidth of 150 fs, incident energy of 15 /spl mu/J and effective NA of 0.007 and laser irradiation time of 10 min for each line. Diffraction gratings of 10 /spl mu/m period and waveguide splitters were fabricated by fs laser. We employed a pulsewidth tunable fs laser system based on CPA architecture which we developed and we will discuss optical properties of the fabricated devices.
