Search for: [Abstrakt = "The newly synthesized polymer, bisphenol A\-aldehyde resin \(BPA\-resin\) has many unique thermo\-optical characteristics. The polymer has high transparency, relatively high refractive index, low birefringence, and large thermo\-optics coefficient at the optical telecommunication wavelengths. Also, the single\-mode channel waveguides have been fabricated using BPA\-resin polymer. The experimental results show, that the polymer waveguide has a low propagation loss of 0.43 and 0.51 dB\/cm at a wavelength of 1.31 and 1.55 mm, respectively, for both TE and TM polarizations. The low polarization dependence loss \(PDL\) of the waveguide was less than 0.1 dB\/cm at above wavelengths, which can be applied in thermal\-optical tuned devices."]
