ABSTRACT:
High-energy pulses of femtosecond lasers form cladding portions of waveguides in bulk glass by producing localized reductions in refractive index. The cladding portions written by the high-energy pulses circumscribe unexposed core portions for defining light-guiding pathways in the bulk glass.
