Polarization-insensitive optical amplifiers in AlInGaAs
IEEE Photonics Technology Letters, 2001We 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.

Wideband Coding Metamaterial with Polarization Insensitivity
2019 Computing, Communications and IoT Applications (ComComAp), 2019In 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 terahertz metamaterial absorber
Optics Letters, 2011We 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 ...

SPIE Proceedings, 2005
Apart from gain dependence on polarization state, phase modulation in semiconductor optical amplifier (SOA) is usually polarization dependent as a result of birefringence. This paper analyzes the factors that determine the polarization dependence of phase modulation and proposes the necessity of fabricating SOA with polarization-insensitive gain and ...
