The analyses of the simulation of a single mode buried waveguide optical phase modulator based on SOI material are here reported. The structure has been simulated by Athena from Silvaco simulation package. The buried waveguide is created by doping phosphorus with concentration of 10e15 cm-3 into the substrate. The real refractive index and the absorption coefficient of the waveguide are changed using the free carrier dispersion effect via carrier injection of a pn junction. The efficiency, VπLπ is calculated and the performance is compared with that of the rib waveguide optical phase modulator of the same material and dimensions. Simulation shows that the device can be an efficient device for application in intensity modulation.

Rib Waveguide

Micro-ring resonator based on silicon-on-insulator (SOI) has been extensively studied due to its many advantages, thus promising to improve the optoelectronic integrated circuit performance. This paper highlights the study of the free carrier injection effect on the silicon rib waveguide with p-i-n diode structure integrated in the SOI micro-ring resonator. The free carrier concentrations have been modulated by the electrical signal that can cause change of refractive index of the micro-ring resonator. The device performances are predicted by using numerical modelling software 2D SILVACO and Finite Difference Time Domain method simulation software RSOFT. The results show the change of refractive index is maximized at a greater applied voltage. A shift in resonant wavelength of around 6.7 nm was predicted at 0.9V with 1.14x10-3refractive index change. It is also shown that 8.5dB change of the output response obtained through the output.
