چکیده
We report optical damage resistant nearstoichiometric Ti:Mg:Er:LiNbO3 single-mode strip waveguides fabricated on congruent LiNbO3 by Er diffusion, Mg/Ti codiffusion, and vapor-transport-equilibration process. The waveguide optical properties, compositions, crystalline phases and Mg, Er and Ti profiles were characterized, and stable signal enhancement has been measured with >200mW pump power. KeywordsTi:Mg:Er:LiNbO3 strip waveguide; Nearstoichiometry; Photorefractive effect; Optical amplifier.

A Simple and Accurate Modal Analysis of Strip- Loaded Optical Waveguides With Various Index Profiles
A simple first-order perturbation approach has been developed to study the propagation characteristics of strip-loaded diffused waveguides with various refractive index profiles. Propagation constants of the guided modes of rib waveguides and strip-loaded waveguides with exponential and Gaussian refractive index profiles are obtained and it is observed that our results are in good agreement wit...
متن کاملAs2S3/Sr(Ti0.7Co0.3)O3 and As2S3/Sr(Ti0.6Fe0.4)O3 strip-loaded waveguides for integrated magneto-optical isolator applications
Sr(Ti0.6Fe0.4)O3 (STF) and Sr(Ti0.7Co0.3)O3 (STC) room-temperature ferromagnetic oxides were grown epitaxially on LaAlO3(001), (LaSr)(AlTa)O3 (001) and Si (001) substrates. Both materials were demonstrated to be magneto-optically active, and more optically transparent at 1550nm wavelength compared with other non-garnet ferromagnetic materials. As2S3/STF and As2S3/STC strip-loaded waveguides wer...
متن کاملLarge tuning of birefringence in two strip silicon waveguides via optomechanical motion.
We present an optomechanical method to tune phase and group birefringence in parallel silicon strip waveguides. We first calculate the deformation of suspended, parallel strip waveguides due to optical forces. We optimize the frequency and polarization of the pump light to obtain a 9 nm deformation for an optical power of 20 mW. Widely tunable phase and group birefringence can be achieved by va...

We report two novel strategies to integrate magneto-optical oxides on oxidized silicon and SOI platforms based on strip-loaded waveguide structures. By using conventional waveguide fabrication and thin film deposition techniques, strip-loaded waveguides for magneto-optical non-reciprocal phase shift (NRPS) applications can be integrated on a silicon platform. As a demonstration, two structures,...
متن کاملNonlinear silicon-on-insulator waveguides for all-optical signal processing.
Values up to gamma=7 x 10(6)/(W km) for the nonlinear parameter are feasible if silicon-on-insulator based strip and slot waveguides are properly designed. This is more than three orders of magnitude larger than for state-of-the-art highly nonlinear fibers, and it enables ultrafast all-optical signal processing with nonresonant compact devices. At lambda=1.55 microm we provide universal design ...
