Unidirectional perfect reflection and radiation in double-lattice photonic crystals
Takuya Inoue, Naoya Noguchi, Masahiro Yoshida +3
Non-Hermitian photonic systems are known to exhibit unique phenomena, where non-Hermiticity is typically introduced by material loss or gain. Here, we propose and experimentally de…
Topological unidirectional guided resonances emerged from interband coupling
Xuefan Yin, Takuya Inoue, Chao Peng +1
Unidirectional guided resonances (UGRs) are optical modes in photonic crystal (PhC) slabs that radiate towards one side without the need for mirrors on the other, represented from…
Analytical Perspective for Photonic Bound States in the Continuum in Photonic Crystal Slabs
Yi Yang, Chao Peng, Yong Liang +2
We investigate the formation of photonic bound states in the continuum (BICs) in photonic crystal slabs from an analytical perspective. Unlike the stationary at- BICs which orig…
Experimental Demonstration of Quasi-Resonant Absorption in Silicon Thin Films for Enhanced Solar Light Trapping
Ardavan Oskooi, Menaka De Zoysa, Kenji Ishizaki +1
We experimentally demonstrate that the addition of partial lattice disorder to a thin-film micro-crystalline silicon photonic crystal results in the controlled spectral broadening…
Tandem Photonic-Crystal Thin Films Surpassing Lambertian Light-Trapping Limit over Broad Bandwidth and Angular Range
Ardavan Oskooi, Yoshinori Tanaka, Susumu Noda
Random surface texturing of an optically-thick film to increase the path length of scattered light rays, first proposed nearly thirty years ago, has thus far remained the most effe…
Partially-disordered photonic-crystal thin films for enhanced and robust photovoltaics
Ardavan Oskooi, Pedro A. Favuzzi, Yoshinori Tanaka +3
We present a general framework for the design of thin-film photovoltaics based on a partially-disordered photonic crystal that has both enhanced absorption for light trapping and r…
