Implementation of SOI-Based Rib Waveguide for High-Speed Optical Interconnect
Keywords:Effective Index (neff), Etch Depth (d), Optical Interconnect (OI), Rib Waveguide, Slab Height (h), Width (W)
AbstractSilicon based photonics have generated strong interest in recent years, mainly in optical waveguide interconnects for microelectronic circuits. This paper presents a single mode condition (SMC) of SOI-based rib waveguide for high-speed Optical Interconnect (OI) implementation at a circuit level. In OptiBPM, a correlation analysis between two parameters, etched rib thickness (r) and effective index (neff) was investigated to identify the effects of width (W) on the rib waveguide. The waveguide performance of the OI links such as output power, propagation loss and propagation delay was recorded based on OptiSPICE simulation. A wavelength (λ) of 1550 nm has the advantages of low power loss and delay which makes it reliable for high-speed OI applications.
