Abstract-There are various techniques for the deposition of SiO 2 films on silicon. Flame Hydrolysis Deposition (FHD) techniques is the most economical technique for the deposition of SiO 2 films. In this technique the SiO 2 films are deposited by hydrolysis of SiCl 4 in a high temperature H 2 -O 2 flame. In the present study we present the growth of SiO 2 films by indigenously developed FHD system and organic compound Tetraethoxyorthosiliate/Tetraethoxysilane TEOS as source of silicon. The films deposited by the FHD system are porous and need annealing at higher temperatures for the densification. We present here for the first time direct dense glassy transparent SiO 2 films deposited by our FHD system. The optical properties of the deposited films were studied by ellipsometery. FTIR spectroscopy was carried out to study the various characteristic peaks of SiO 2 bonds. The peaks corresponding to Si-O-Si stretching, bending and rocking modes are observed at 1090 cm −1 , 812 cm −1 and 463 cm −1 respectively. The absence of peaks corresponding to the OH bond in the deposited film reveals that the deposited films are most suitable for the photonic devices application. The surface analysis was carried out using SEM. The EDAX of the deposited film confirms the composition of the Si and O in the deposited film.

“…In contrast to this approach, the Y-branch splitters use a cascade of one-by-two waveguide branches (also called Y-branches) (Nourshargh et al 1989). Anyhow, the processing of the branching point, where two waveguides start to separate, is technologically very difficult (Soldano et al 1992).…”

Modeling and optimization of 1 × 32 Y-branch splitter for optical transmission systems

The goal of this paper is to design a low-loss 1 9 32 Y-branch optical splitter for optical transmission systems, using two different design tools employing Beam Propagation Method. As a first step, a conventional 1 9 32 Y-branch splitter was designed and simulated in two-dimensional environment of OptiBPM photonic tool. The simulated optical properties feature high loss, high asymmetric splitting ratio and a large size of the designed structure, too. In the second step of this work we propose an optimization of the conventional splitter design leading to suppression of the asymmetric splitting ratio to onethird of its initial value and to the improvement of the losses by nearly 2 dB. In addition, 50% size reduction of the designed structure was also achieved. This length-optimized low-loss splitter was then modelled in a three-dimensional environment of RSoft photonic tool and the simulated results confirm the strong improvement of the optical properties.

“…For low numbers of splittings ( N < 16) the splitter could be made as a fused bundle of optical fibers [l] but, for larger numbers of splittings integrated optical solutions [2]-[4] become attractive. The most obviuos way of designing an optical waveguide power splitter would be to make it as a cascade of 1-by-two waveguide branches [2].…”
