Abstract

Near surface channel waveguides have been fabricated in Neodymium doped YAG ceramics by using IR femtosecond laser irradiation at the low frequency regime. Single mode guidance has been demonstrated with propagation losses of ~1 dB/cm. Time resolved confocal micro-luminescence experiments have been used to determine the spectroscopic properties of the Nd3+ laser ions in the channel waveguide as well as to elucidate the waveguide formation processes.

Peak position and FWHM of the most isolated emission peak within the 4F3/24I11/2 band (λ=1.052 μm). The results obtained along Scan 1 and Scan 2 in Fig. 1(a) correspond to Figures 3(a) and 3(b), respectively. Colored bands inside Fig. 3 indicate the spatial extension of the surface channel waveguide modal intensity distribution as seen from Fig. 1(b).
