Optical properties of one-dimensional soft photonic crystals with ferrofluids

Realization of efficient radiative cooling in thermal emitter with inorganic metamaterials

“…The bottom slit of triangular prisms enhances the absorption in the second atmospheric window. The existence of surface triangular prism leads to the redistribution of the electric field at the top layer [38]. It has been verified by increasing the height d 1 of the triangular prisms, namely, the triangular prisms are close enough to form a square in adjacent periods, the absorption spectrum before 7 µm remains unchanged, but the absorption near 10 µm clearly decreases by 20%.…”

Tunable flat band slow light in reconfigurable photonic crystal waveguides based on magnetic fluids

“…Recently, magnetic fluids (MFs) as plain colloidal materials in magnetics get renewed and extensive interests in optics with the increasing development of optical communications, optical sensing and nanoscience and technology [30][31][32][33][34][35][36][37][38][39]. We have proposed to achieve the extremely large bandwidth and ultralow-dispersion slow light in PC waveguides with MFs as the background [40].…”

“…[6][7][8][9] . Notably, colloid ferrofluid was used as the basic material to design one-dimensional (1D) photonic crystal and magnetic control 1D photonic crystals [2,5] . Photonic crystal fiber filled with Fe 3 O 4 nanoparticles, which was temperature adjustable, was also reported [3] .…”

“…There was a defect layer filled with nanoparticle magnetic fluid in the photonic crystals. The transmission spectrum of photonic crystal with a defect layer-filled nanoparticle magnetic fluid was calculated numerically using the transmission matrix method [5] . The magnetic field tunable characteristic for the wavelength of defect localized modes was studied.…”
