How the Bubble Lens Works

Caption

A nanoscale light beam modulated by short electromagnetic waves, known as surface plasmon polaritons -- labelled as SPP beam -- enters the bubble lens, officially known as a reconfigurable plasmofluidic lens. The bubble controls the light waves, while the grating provides further focus.
