Abstract

A directional coupler written in a glass sample by the focused 400-nm output from a 25-fs oscillator is reported. The coupler is single mode; the splitting ratio is 1.9  dB at 633  nm. A refractive-index profile of the waveguide with a magnitude of Δn=4.5×10-3 was retrieved from a near-field mode pattern.
