Fabrication of integrated Ti:LiNbO3 waveguide polarizer
نویسنده
چکیده
The design and fabrication of an integrated waveguide polarizer in z-cut LiNbO3 crystals are reported. Singlepolarization guiding is achieved by careful selection of Ti diffusion parameters exploiting the transverse electric/ transverse magnetic TE/TM refractive index anisotropy. Fabricated Ti:LiNbO3 waveguide polarizers of 1.5 cm length exhibit less than 0.2-dB/cm propagation loss at TM and 33-dB extinction ratio as measured at 1.55m wavelength. © 2008 Society of Photo-Optical Instrumentation Engineers.

A semi-analytical technique to determine the propagation constant of periodically segmented Ti:LiNbO3 waveguide (PSW) is described. The 2-D refractive index profiles of the waveguide segments are computed from its fabrication parameters, such as, Ti-layer thickness and width, and the diffusion parameters. WKB method is used to transform 2-D refractive index profile to 1D lateral effective index...

متن کاملCompact and integrated TM-pass waveguide polarizer.
A novel integrated TM-pass waveguide polarizer with a subwavelength-wide slot is introduced and theoretically analyzed. With a proper design of the slot, the waveguide can be used as a single polarization waveguide to guide only TM polarization modes of the light signal. With 26 microm length of this TM-pass polarizer, our computer simulations predict the insertion loss of 0.54 dB for the TM po...
