Abstract
A method for producing a modulated optical signal from a droplet of a liquid medium. The method positions a droplet of liquid on a hydrophobic surface, in the path of an optical beam, and modulates the shape of the droplet on this surface, by electrowetting, to modulate the signal obtained after passing the optical beam through the droplet.

A method of optically analyzing a droplet of a liquid medium, comprising:
- forming a modulated optical signal coming from a droplet of a liquid medium by:
- positioning a droplet of liquid on a hydrophobic surface, in the path of an optical beam,
- modulating the shape of the droplet on the hydrophobic surface, by electrowetting, to modulate the signal obtained after passing the optical beam through the droplet, and
- then demodulating the signal obtained on exiting the droplet.
