Characterization of optical waveguides produced with 530 nJ pulses and UO lens focusing at 250 µm of depth. (a) Transmission and (b) reflection cross-section optical microscopy, (c) near field image of the guided mode at 1640 nm, (d) longitudinal (top view) optical microscopy, (e) EDX elementary mapping and (f) EDX profile measured along the vertical line indicated in (e). Scale bar on (c) applies to all images. Laser beam direction is indicated by the red arrow in (a).
