2Metamaterial-based octave-wide terahertz bandpass filters显示文摘We present octave-wide bandpass filters in the terahertz(THz)region based on bilayer-metamaterial(BLMM)structures.The passband region has a super-Gaussian shape with a maximum transmittance approaching 70%and a typical stopband rejection of 20 dB.The design is based on a metasurface consisting of a metallic squarehole array deposited on a transparent polymer,which is stacked on top of an identical metasurface with a subwavelength separation.The superimposed metasurface structures were designed using finite-difference time-domain(FDTD)simulations and fabricated using a photolithography process.Experimental characterization of these structures between 0.3 and 5.8 THz is performed with a time-domain THz spectroscopy system.Good agreement between experiment and simulation results is observed.We also demonstrated that two superimposed BLMM(2BLMM)devices increase the steepness of the roll-offs to more than 85 dB/octave and enable a superior stopband rejection approaching 40 dB while the maximum transmittance remains above 65%.This work paves the way toward new THz applications,including the detection of THz pulses centered at specific frequencies,and an enhanced time-resolved detection sensitivity toward molecular vibrations that are noise dominated by a strong,off-resonant,driving field.ALI MALEKI AVINASH SINGH AHMED JABER WEI CUI YONGBAO XIN BRIAN T.SULLIVAN ROBERT W.BOYD JEAN-MICHEL MÉNARD 2023Photonics Research2023,11,4:0
