Abstract :
A novel, sophisticated and versatile periodically poled lithium niobate (PPLN) waveguiding structure is designed to operate as an all optical-transistor, at environmental temperature and in the second band of fiber optic communication. The interaction among guided and leaky modes is obtained by means of two different techniques: (i) birefringence mode-matching and (ii) quasi-phase-matching by periodically poling the lithium ferroelectric domains. The correct operation of the device at the wavelength of 1320 nm requires a strong diffusion of Mg in the region external to the periodically poled waveguiding channel, even in order to maximize the bounding of the EM field and the overlapping integrals
