Caption: This image shows an actual cross-section and extreme magnification of the nanomechanical fiber. The dual cores are shown in the center, each a mere 0.5 micrometers across at their centers, while the supporting glass filament is approximately 0.2 micrometers across. The small-scale structure was achieved by heating and drawing out a larger fiber-optic form.
