Heterodyne displacement interferometer, insensitive for input polarization

Optics Letters, 2014
Periodic nonlinearity (PNL) in displacement interferometers is a systematic error source that limits measurement accuracy. The PNL of coaxial heterodyne interferometers is highly influenced by the polarization state and orientation of the source frequencies.

A Polarization Insensitive Wide‐Band Perfect Absorber

Advanced Engineering Materials, 2019
In this article, a wide‐band and polarization‐insensitive perfect absorber composed of 4 sandwiched layers of dielectric and metal disks is introduced. Compared to classical perfect absorbers, the system supports near‐unity absorption within a wider spectral window through multiple perfect absorption mechanisms that exist due to a constituting inter ...

Polarization-sensitive photodetectors based on three-dimensional molybdenum disulfide (MoS2) field-effect transistors

Nanophotonics, 2020
The molybdenum disulfide (MoS2)-based photodetectors are facing two challenges: the insensitivity to polarized light and the low photoresponsivity. Herein, three-dimensional (3D) field-effect transistors (FETs) based on monolayer MoS2 were fabricated by ...

Polarization insensitive perfect absorber with nanorod arrays

, 2014
We propose a polarization insensitive near infrared perfect absorber (PA) based on the localized surface plasmon resonances (LSPRs) of nanorod arrays. Polarization insensitivity of our PA structure is achieved by combining two sets of nanorods with x and
