Resumen:
ABSTRACTWe report a new approach to themicrofabrication of
permanent optical waveguide arrays inside fused silica induced
by focusing infrared femtosecond laser pulses with microjoule
energy. These arrays consist of waveguides limited by voidlike
damage zones with very loose coupling among adjacent
guides, thus allowing the excitation of a single one. The proposed
method shows the possibility of using created void-like
structures for both the fabrication of integrated optical devices
as well as for the control of previously induced refractive index
change regions.We report a new approach to themicrofabrication of
