In this paper, we examine the impact of three-dimensional grating layers embedded at selected locations in an organic solar cell structure to obtain enhanced efficiency. The design, simulations, and optimizations were carried out using an in-house to

When observing sea water, a specular reflection of a light source may appear in the form of bright points of light that come and go. These bright points of light, called glints, blend together to form a smooth path of glittering light when viewed fro

We introduce a 5µm-thick meta-structure design showing ~100% ultra-narrow, angular-sensitive resonant absorptance, MWIR peaked with Q ≈ 2650 for tunable sensing applications. Light trapping inside a 22nm absorber is visualized by Poynting vector v

A new resonant-cavity photodetector architecture, where mirrors are surrogated by grating-patterned meta-surfaces is suggested. We show by design that thus structured, sub-10pm thick mid-IR photodetectors, with 75nm thick HgCdTe photo-absorber, can a

A few-micron thick structure that shows nearly 100% resonant polarized absorptance at a predefined midinfrared wavelength is designed and simulated. Like resonant-cavity enhanced photodetector structure, it contains a thin absorber enclosed in a diel

We study a triangular arrangement of two flat mirrors and a grating mirror for coupling a $$-1{\mathrm{st}}$$ diffracted order light beam into a traveling-wave intra-cavity light recirculation and out-of-cavity output, combining the $$0\,{\mathrm{th}

Optical absorbers, comprising a thin semiconductor layer placed between two transparent ones in close proximity to a subwavelength grating, are considered. With no back mirror, these structures only mimic the resonant cavity enhanced photodetector, b

We propose and design high efficiency thin Photodetectors (PDs), using micro-cell gratings, which enable near-field enhanced (NFE) mid IR absorption by confining the EM fields to the absorber region. These PD types have a different operation principl
