Abstract
A directional coupler written in a glass sample by the focused 400-nm outpu t from a 25-fs oscillator is reported. The coupler is single mode; the spli tting ratio is 1.9 dB at 633 nm. A refractive-index profile of the waveguid e with a magnitude of Deltan = 4.5 x 10(-3) was retrieved from a near-field mode pattern.
