Make all your photonics from perovskite?

Aug. 14, 2014
Have we finally found the universal substance for photonics? Well, not really. But perovskite, the material (actually, a class of materials) that's recently been getting technical press for its high efficiency as a solar-cell material, has other potential uses as well.

Have we finally found the universal substance for photonics? Well, not really. But perovskite, a material (actually, a class of materials with a common structure) that's recently been getting technical press for its high efficiency as a solar-cell material, has other potential uses as well.

Here's the solar-cell (and thus photodetector) angle:

Next, LEDs:
LEDs made from perovskite could enable low-cost LED displays

Lasers:
High-efficiency perovskite photovoltaic material also lases

Nonlinear optical devices:

Metamaterial lenses:
Also from Optical Materials Express: http://dx.doi.org/10.1364/OME.4.001186

It seems you can use perovskites for everything in your optical system except the mechanical devices. But wait:

Piezoelectric actuators:
Fujifilm creates new PZT actuator film with higher piezoelectric constant

So it is my pleasure to announce (OK, in jest) the launch of a new sister brand, Perovskite Focus World. And if you want to receive the print version, be prepared: in the interests of saving paper, it will be made from . . .
