Abstract:
We review recent results on a novel method to modify crystalline dielectric materials and fabricate optical waveguides and integrated optics devices. It relies on irradiation with medium-mass high-energy ions (2–50MeV) where the electronic stopping power is dominant over that one associated to nuclear collisions. By exploiting the processing capabilities of the method, novel optical structures can be achieved at moderate (1014cm−2) and even low and ultralow (1012cm−2) fluences. In particular, step-like waveguides with a high index jump Δn∼0.1–0.2, guiding both ordinary and extraordinary modes, have been prepared with F and O ions (20MeV) at moderate fluences. They present good non-linear and electrooptic perfomance and low losses. (1dB/cm). Moreover, useful optical waveguiding has been also achieved at ultralow frequencies (isolated track regime), using Cl and Si ions (40–45MeV). In this latter case, the individual amorphous nanotracks, whose radius increases with depth, create an effective optical medium causing optical trapping.
