We propose an adaptive dielectric liquid microlens whose focal length can be tuned from negative to positive or vise versa. The biconcave polymer base in the lens cell not only generates an inhomogeneous electric field, inhibits drifting of the droplet, and reduces the operating voltage but also induces a negative optical power. Pairing with the top subliquid lens, the whole lens exhibits a tunable...
In this paper, we demonstrated two kinds of variable photonic devices: microlens and phase modulator. Both of them work based on the principle of dielectric-force-induced surface deformation. For each device, we depict its structure as well as the device fabrication processes. Their performances were tested and evaluated using optical microscope. Based on our investigation, such a deformable liquid...
