Polarization-insensitive optical amplifiers in AlInGaAs

IEEE Photonics Technology Letters, 2001
We report the theoretical modeling and the fabrication of polarization-insensitive optical amplifiers at 1300 nm in AlInGaAs-InP material system. Gain calculations, using the k.p method, show that the introduction of 0.33% tensile strain into a three-quantum-well structure can achieve gain-matching over a wide energy spectrum.

Polarization insensitive terahertz metamaterial absorber

Optics Letters, 2011
We present the simulation, implementation, and measurement of a polarization insensitive resonant metamaterial absorber in the terahertz region. The device consists of a metal/dielectric-spacer/metal structure allowing us to maximize absorption by varying the dielectric material and thickness and, hence, the effective electrical permittivity and ...

Wideband Coding Metamaterial with Polarization Insensitivity

2019 Computing, Communications and IoT Applications (ComComAp), 2019
In this paper, a wideband coding metamaterial (CDM) is proposed for radar cross-section (RCS) Reduction. The proposed coding units have three advantages: (1) Simple design. Dual-polarized ‘0’ and ‘1’ coding elements (CEs) are realized by a pair of rectangle patch over 7-14.6 GHz (bandwidth 70%). The ‘0’ and ‘1’ CEs represent reflected phases 0° and 180°

Polarization-insensitive ultra-short waveguide taper

Optics Letters, 2021
Waveguide taper, a key component in the photonic integrated circuit (PIC), enables on-chip mode conversion, but large-footprint tapers are detrimental to the PIC, which desires compact and efficient devices. Polarization sensitivity also limits the tapers in the applications involving orthogonal modes.
