The technological process, based on ion implantation and selective etching, for producing ridge waveguides on Lithium Niobate substrates is described and successfully applied. The parameters of the fabricated samples are used in a comprehensive FEM-based modal analysis of an Erbium-doped Lithium Niobate ridge waveguide. Simulation results support the concept of strong mode confinement at pump wavelength...
The self-pulsing laser reported here was fabricated in a 92 mm long Er-diffusion doped Z-cut LN substrate with a surface concentration of about 1.24 x 1020 cm-3 and a diffusion depth of 8.4 mum. Ti stripes of 7 mum width were indiffused to define single mode waveguides for the 1550 nm wavelength range. The laser cavity was formed by two dielectric multilayer mirrors, one of them vacuum-deposited on...
