Abstract
Single-mode X couplers and three-dimensional waveguides are fabricated in t ransparent glasses by use of an unamplified femtosecond laser generating en ergies of up to 100 nJ. Changing fabrication parameters such as power and s canning speed permits creation of waveguides with a wide range of structure s and refractive-index difference. Optical coherence tomography shows large refractive-index changes of up to similar to 10(-2) in the waveguides; the se changes are consistent with guided mode analysis.
