In conclusion, it is seen that FSR increased as the core width increases and FSR decreases as the core height and the rib height increased.
When the width of the core increased, Q-factor initially increased before decreasing and increasing again.
As the height of the core and rib increased, Q-factor also increased.
Lastly, Q-factor is 1573 as the height of buried oxide is increased. As a conclusion, it is recommended to design a SOI waveguide at the core width of 450nm, the core height of 210nm and the rib height of 70nm in which there is a good compromise between FSR, FWHM and Q-factor. |
