“…45 and 27% peak external quantum efficiencies were achieved for the two devices, respectively. In 2021, Kamboj et al (2021) in the D. Wasserman’s group also reported a fully epitaxially guided mode resonant mid-wave IR type II superlattice nBn photodetector consisting of a high refractive index absorber/waveguide layer, a low refractive index semiconductor absorber layer and a heavily doped reflector layer. The experimental results show that the absorption is strongly enhanced at the wavelengths coupled to the guided mode resonance.…”

Micro-Nano optics is one of the most active frontiers in the current development of optics. It combines the cutting-edge achievements of photonics and nanotechnology, which can realize many brand-new functions on the basis of local electromagnetic interactions and become an indispensable key science and technology of the 21st century. Micro-Nano optics is also an important development direction of the new optoelectronics industry at present. It plays an irreplaceable role in optical communication, optical interconnection, optical storage, sensing imaging, sensing measurement, display, solid-state lighting, biomedicine, security, green energy, and other fields. In this paper, we will summarize the research status of micro-nano optics, and analyze it from four aspects: micro-nano luminescent materials and devices, micro-nano optical waveguide materials and devices, micro-nano photoelectric detection materials and devices, and micro-nano optical structures and devices. Finally, the future development of micro-nano optics will be prospected.

“…Since the periodicity of the GMR structure itself is much smaller than the wavelength of interest, we expect to see only specular reflection in the considered wavelength range ( 37 ). We note that the linewidth of the resonance created by the GMR structure is sensitive to both the patterned area widths (Λ/2) and the scattering rate of the n -InAs underneath ( 38 ).…”

Nonreciprocal infrared absorption via resonant magneto-optical coupling to InAs

et al. 2022

Nonreciprocal elements are a vital building block of electrical and optical systems. In the infrared regime, there is a particular interest in structures that break reciprocity because their thermal absorptive (and emissive) properties should not obey the Kirchhoff thermal radiation law. In this work, we break time-reversal symmetry and reciprocity in n-type–doped magneto-optic InAs with a static magnetic field where light coupling is mediated by a guided-mode resonator structure, whose resonant frequency coincides with the epsilon-near-zero resonance of the doped indium arsenide. Using this structure, we observe the nonreciprocal absorptive behavior as a function of magnetic field and scattering angle in the infrared. Accounting for resonant and nonresonant optical scattering, we reliably model experimental results that break reciprocal absorption relations in the infrared. The ability to design these nonreciprocal absorbers opens an avenue to explore devices with unequal absorptivity and emissivity in specific channels.

“…Free-carrier induced reduction in the refractive index has long been known and leveraged in plasmon-enhanced waveguides for quantum cascade lasers [28], as well as more recently in ultra-thin guided mode resonance detectors. [29] Here, we explore the viability of highly-doped semiconductors as low-index layers in DBRs for MWIR, GaSb-based devices. We show theoretically that the reduction in the refractive index yields high reflectance DBRs with reduced thickness in comparison to AlAsSb/GaSb DBRs.…”
