Materials for optics

Definition

Materials for optics are substances used to manipulate the flow of light. This can include reflecting, absorbing, focusing or splitting an optical beam. The efficiency of a specific material at each task is strongly wavelength dependent, thus a full understanding of the interaction between light and matter is vital.

    Simultaneous trapping, alignment and anti-Stokes fluorescence cooling of Yb3+:YLF nanocrystals from room temperature to temperatures as low as about 130 K can now be realized using a single-beam optical dipole trap within a low-pressure environment.

    Switching the handedness of circularly polarized light requires separately controlling the phases of orthogonal components while maintaining their magnitudes, ideally with gigahertz operation rates. Ultrafast switching has now been realized via all-optical control of birefringent metamaterials.
