Multi-Core Fiber Creates Optical Supermode for Larger Effective Area
Technology Benefits
Increased transmission capacity
Technology Application
Optical communication systems
Detailed Technology Description
According to Xia (2011), for single-mode operation, CMCFs can attain larger effective index difference (ΔNeff) and effective area (Aeff) than FMFs. As a result, CMCFs tend to have less mode coupling and nonlinearity, which is important for efficient long-haul transmission. This invention is a passive, coupled multi-core fiber wherein the cores each support a spatial mode and are positioned close enough to cause coupling between their modes, generating supermodes capable of transmitting data.
