Abstract:
Results on an optical waveguide filter operating in the near IR region are reported. The device consists of a hybrid sol-gel -based grating loaded waveguide, obtained through the merging of conventional photolithography and UV-nanoimprinting. Starting from submicrometric gratings, fabricated by electron beam lithography, a soft mould has been produced and the original structures were replicated onto sol-gel photosensitive films. A final photolithographic step allowed the production of grating-loaded channel waveguides. The devices were optically characterized by transmission measurements in th

Plasma etching procedures were made in steps to reduce roughness at the laterals and sidewalls of waveguides.

These sites serve to selectively nucleate the thermal decomposition of TIBA which results in the growth of high quality Al filns (resistivities ∼5 μΩ-cm).

The pulsed plasma duty cycle (ON/OFF) resulted in higher dielectric constant DCTMDS films for higher duty cycles. The variation of dielectric constants does not show any trend with varying film thicknesses, indicating that the thickness of the deposited films is no
