ABSTRACTResults are presented for the propagation loss of planar optical waveguides fabricated in SIMOX structures with Si overlayers whose thickness varies from 0.57 μm to 6.0 μm. The results demonstrate that thick Si overlayers are required to produce propagation losses below 1 dB/cm. In addition, the results of the coupling between two vertically integrated waveguides formed using two buried SiO2 layers are also reported.

Nanoparticles composed of magnesium fluoride were successfully introduced into polymer matrices used for the fabrication of planar optical waveguides. Optical layers without visible scattering were successfully prepared. The transparent nanocomposites were formulated by direct mixing of modified MgF2 nanoparticles with fluorinated co-polymer matrix or acrylate monomer mixture with a help of additional solvent. An addition of MgF2 nanoparticles results in decrease of refractive index and thermo-optic coefficient of the polymer but increases substantially the optical propagation losses for planar waveguide at 1547 nm.

Planar Optical Waveguides

Optical waveguides are the key component for distributing optical signals with very low propagation loss in optical communication. Several type optical waveguides are established currently such as silica optical fiber. In the planar structure, planar optical waveguides are suitable for implementing to integrated optic applications. In here, rectangular optical waveguides on a planar structure with a LiTaO3 crystal as the substrate are described. The optical waveguides were designed for single mode operation at infrared optical wavelength. The Marcatili method is used for designing by separated the rectangular optical waveguides into two slab optical waveguides. Design rules for the rectangular optical waveguides are discussed in this paper

ABSTRACTIn this paper the fabrication process and characteristics of waveguides produced by He+ implantation in Y-cut X- and Z-propagating LiNbO3 are presented It is shown that low propagation losses, down to 1dB cm−1 at λ = 633μm can be obtained for TM modes only in Y-cut X-propagation samples whilst Y-cut Z propagating samples support both TE and TM modes with relatively low losses.
