Abstract :
Planar waveguides of erbium doped ZnF2 on MgF2 substrate have been grown using molecular beam epitaxy and channel waveguides have been formed by ion milling. By exciting individual channels with an 800 nm pump, strong upconversion fluorescence has been generated at 410, 550 and 670 nm and at numerous weaker peaks. The fabrication technique can be adapted to semiconductor substrates for making compact diode-pumped visible and infra-red lasers.
