Nanosecond mid-infrared pulse generation via modulated thermal emissivity
Yuzhe Xiao, Nicholas A. Charipar, Jad Salman +2
We demonstrate the generation of nanosecond mid-infrared pulses via fast modulation of thermal emissivity, enabled by the absorption of visible pump pulses in unpatterned silicon a…
Multi-refractive-index metamaterials based on subwavelength waveguide arrays
Zhaoning Yu, Chenghao Wan, Jad Salman +4
We demonstrate a metamaterial that cannot be described by a single set of refractive-index and impedance values, even for fixed frequency and polarization. The metamaterial structu…
Nanophotonic engineering of far-field thermal emitters
Denis G. Baranov, Yuzhe Xiao, Igor A. Nechepurenko +3
Thermal emission is a ubiquitous and fundamental process by which all objects at non-zero temperatures radiate electromagnetic energy. This process is often presented to be incoher…
Mid-infrared optics using dielectrics with refractive indices below unity
Alireza Shahsafi, Yuzhe Xiao, Jad Salman +4
Conventional transparent materials at optical frequencies have refractive index values (n) greater than unity -- most commonly between about 1 and 4. This paper explores optical ph…
