Phase-change materials (PCMs) have emerged as promising active elements in silicon (Si) photonic systems. In this work, we design, fabricate, and characterize a hybrid Si-PCM optical modulator. By integrating vanadium dioxide (a PCM) within a Si photonic waveguide, in a non-resonant geometry, we demonstrate ~ 10 dB broadband modulation with a PCM length of 500 nm.

Polarization beam splitters, devices that separate the two orthogonal polarizations of light into different propagation directions, are among the most ubiquitous optical elements. However, traditionally polarization splitters rely on bulky optical materials, while emerging optoelectronic and photonic circuits require compact, chip-scale polarization splitters. Here, we show that a rectangular lattice of cylindrical silicon Mie resonators functions as a polarization splitter, efficiently reflecting one polarization while transmitting the other. We show that the polarization splitting arises from the anisotropic permittivity and permeability of the metasurface due to the twofold rotational symmetry of the rectangular unit cell. The high polarization efficiency, low loss and low profile make these metasurface polarization splitters ideally suited for monolithic integration with optoelectronic and photonic circuits.

Effective in-line cure monitoring is crucial for quality and cost optimization of carbon fiber reinforced (CFR) composites manufacturing. The capability to ensure high quality and low cost production of CFR composites through improved monitoring methods will make the material more accessible to various industries. In the present study, 3D scanning laser Doppler vibrometry (LDV) is used as a means of remote, non-invasive monitoring of the degree of cure in unidirectional CFR epoxy prepreg tape. Analysis of the surface velocity of the test samples shows the changes in vibration characteristics that relate to the viscoelastic properties of the material. These properties are directly affected by phase transitions that occur as the sample cures. Differential scanning calorimetry (DSC) is used to develop a baseline model against which the laser vibrometry data are analyzed. The presented findings will be leveraged in further development of real-time cure monitoring technologies.

Controlling functionalities, such as magnetism or ferroelectricity, by means of oxygen vacancies (VO) is a key issue for the future development of transition-metal oxides. Progress in this field is currently addressed through VO variations and their impact on mainly one order parameter. Here we reveal a mechanism for tuning both magnetism and ferroelectricity simultaneously by using VO. Combining experimental and density-functional theory studies of Eu0.5Ba0.5TiO3−δ, we demonstrate that oxygen vacancies create Ti3+3d1 defect states, mediating the ferromagnetic coupling between the localized Eu 4f7 spins, and increase an off-center displacement of Ti ions, enhancing the ferroelectric Curie temperature. The dual function of Ti sites also promises a magnetoelectric coupling in the Eu0.5Ba0.5TiO3−δ.
