In recent past, silicon photonics has been one of the most fascinating topics in communication worldĄŻs in which tremendous impacts have been realized by utilizing Silicon-On-Insulator (SOI) platform with very thin top layer of silicon.
SOI platform are often recognized on behalf of its high index contrast and compatibility with Complementary Metal-Oxide-Semiconductor (CMOS) technology.
The most standard design of single mode SOI nanowire commonly have a cross section of approximately 500nm x 220nm.Optical waveguide such as SOI based platform waveguide is acknowledged as the most extensive bridging element in optical integrated devices.
Therefore upon, a low loss optical waveguide is important in the design and fabrication of reliable and effective optical communication system.
Low loss optical waveguides can be attained by applying or varying various parameters.
With low loss optical waveguide structure, low processing cost can be achieved with low-cost device during fabrication process.
Among these types of optical filters, MRR based structure is recognize as superior as a result of high Q-factor, high transmission at resonance and high extinction ratio. |
