Large area compatible broadband superabsorber surfaces in the VIS-NIR spectrum utilizing metal-insulator-metal stack and plasmonic nanoparticles
(OSA - The Optical Society, 2016)Plasmonically enhanced absorbing structures have been emerging as strong candidates for photovoltaic (PV) devices. We investigate metal-insulator-metal (MIM) structures that are suitable for tuning spectral absorption ... -
Multispectral plasmonic structures using native aluminum oxide and aluminum
(OSA, 2017)We report the use of native aluminum oxide to fabricate periodic metal-insulator-metal resonators with simultaneous resonances in the visible and IR wavelengths. The cavity size is in the order of λ3/25000 in the NIR. -
Perfectly absorbing ultra thin interference coatings for hydrogen sensing
(OSA - The Optical Society, 2016)Here we numerically demonstrate a straightforward method for optical detection of hydrogen gas by means of absorption reduction and colorimetric indication. A perfectly absorbing metal-insulator-metal (MIM) thin film ... -
Plasmonically enhanced hot electron based photovoltaic device
(Optical Society of American (OSA), 2013)Hot electron photovoltaics is emerging as a candidate for low cost and ultra thin solar cells. Plasmonic means can be utilized to significantly boost device efficiency. We separately form the tunneling metal-insulator-metal ... -
Semiconductor-less photovoltaic device
(IEEE, 2013)We demonstrate a novel semiconductor-less photovoltaic device and investigate the plasmonic effects on this device structure. The device is made of metal and dielectric layers and the operation is based on hot carrier ... -
Sensitivity comparison of localized plasmon resonance structures and prism coupler
(2014)Plasmon resonances are widely used in biomolecular sensing and continue to be an active research field due to the rich variety of surface and measurement configurations, some of which exhibit down to single molecule level ... -
Visible light nearly perfect absorber: an optimum unit cell arrangement for near absolute polarization insensitivity
(OSA - The Optical Society, 2017)In this work, we propose an optimum unit cell arrangement to obtain near absolute polarization insensitivity in a metal-insulator-metal (MIM) based ultra-broadband perfect absorber. Our findings prove that upon utilizing ...
