This work reports a variable attenuator/waveplate based on thermo-optic (TO) effect induced on a waveguide patterned by direct UV-laser writing on films of organic-inorganic di-ureasil hybrids. The waveguide temperature was tuned inducing phase retardation between the transverse electric (TE) and transverse magnetic (TM) modes, resulting in a controllable waveplate. Furthermore, the waveguide TO actuation...
In this work, a series of transparent di-ureasil hybrids containing different amounts of methacrylic acid modified zirconium tetrapropoxide (ZrMcOH) nanoclusters (5–85mol%) and incorporating EuCl 3 and [Eu(tta) 3 (H 2 O) 2 ] (tta=thenoyltrifluoroacetonate) complex were prepared. These hybrids are multi-wavelength emitters due to the convolution of the host intrinsic...
Organic-inorganic hybrids were tailored as transparent monoliths and as planar waveguides deposited on borosilicate substrates by the spin coating technique. Laser direct writing process was used to create monomode Y-splitters. The Y-splitter structures were designed and optimized for a coupling ratio of 50% using a beam propagation method (BPM) software.. The potential of these optical structures...
