Dual suspended core optical fiber was fabricated and demonstrated by researchers at the Optoelectronics Research Centre, University of Southampton in the UK. This fiber has unique function that any other fibers not able to achieve easily, not only transmit light, also the two cores can mechanically move and interact with each other. This MEMS-type of optical fiber was made from lead silicate glass.
The sub-micron optical fiber is highly sensitive to pressure, vibration etc. and would offer interesting applications in the broad field of sensing.
