Plasmonic Mach-Zehnder Interferometer for Optical Fiber

SUMMARY

Nanoplasmonic structures are believed to be promising for high throughput and low cost sensing applications; however there are no products on the market that can offer this capability. As such, Lehigh University has attempted to offer a solution by investigating methods to integrate plasmonic Mach-Zehnder Interferometery in an optical fiber to produce detectable signals. The sensitivity of this technology is comparable, and likely better than conventional surface plasmon resonance systems. A primary objective is to integrate the technology with an optical fiber sensor.

THE MARKET

The worldwide market for biosensors was $6.72 billion in 2009, growing at an annual rate of over 11% until 2016, where it is estimated to reach $14.42 billion. [1] Applications for biosensors are growing, increasing demand and revenues for these technologies. [2]  There is also a push in the market for miniaturized biosensor devices in order to integrate them into portable systems, providing a window of opportunity for new technologies entering the market with such an “on-chip” focus.
