Abstract

Waveguides in the form of connected pearls, written with sub-30 fs pulses centered at 800 nm at a repetition rate of 10 MHz, show high changes of the refractive index and, as a consequence, simple in-coupling. The value of the refractive index modification of these waveguides is as high as 10-2, optical losses are 6 dB/cm (at 1.55 μm) and the mode field diameter is 8 μm at 670 nm.
