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.

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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
