Nanostructured spectral filters enabling dynamic color-tuning are saliently attractive for implementing ultra-compact color displays and imaging devices. Realization of polarization-induced dynamic color-tuning via one-dimensional periodic nanostructures is highly challenging due to the absence of plasmonic resonances for transverse-electric polarization. Here we demonstrate highly efficient dy...

We have developed a polarization microscope based on a commercial transmission microscope. We replace the halogen light source by a collimated LED light source module of six different colors. We use achromatic polarized optical elements that can cover the six different wavelength ranges in the polarization state generator (PSG) and polarization state analyzer (PSA) modules. The dual-rotating wa...

Highly efficient polarization-tuned structural color filters, which are based on a one- dimensional resonant aluminum grating that is integrated with a silicon nitride waveguide, are proposed and demonstrated to feature a broad color palette. For such a metallic grating structure, transmissive color filtering is only feasible for the incident transverse-magnetic (TM) polarization due to its hig...

polarization for au/pb(zr ti )o /yba cu o ferroelectric capacitor has been studied and measured by pulse method. a sequence of pulses with amplitudes varying from 0 to 10 volts in 2 volt steps is applied and a conventional polarization curve is obtained by integrating the charge flow from the polarization switching induced by the voltage ramp. a value of 25?c/cm2 is measured for the saturated p...

18 P hotons come in many beautiful colors and are very useful for transmitting information with little loss over large distances. However, photons are also a little boring: they essentially do not interact with one another. This absence of interactions, or equivalently, the linearity of the optical response, is what allows one to send powerful optical pulses over large distances through optical...

Organs of fish, amphibian, reptile, bird and mammals when stained by Sirius Red and studied with polarization microscopy present different colors in regions where collagens I, II and III have been described. Collagen type I presented a yellow, orange or red color while collagen type III appeared green. Collagen type II, present in cartilage and chondrosarcoma showed a variable color according t...

Two-dimensional matrix of subwavelength dot structures are directly generated on molybdenum surfaces by focusing two-color femtosecond laser pulses through an optical lens. In contrast to the traditional fabrication approaches, the spatial periodicities of such surface structures are demonstrated to rely on the time delay of two laser beams through transient correlation between their ultrafast ...
