A Polarization Insensitive Semiconductor Optical Amplifier

IEEE Photonics Technology Letters, 2016
This letter proposes an integrated InGaAsP-InP/silicon-on-insulator (SOI) polarization insensitive semiconductor optical amplifier (SOA). The SOA consists of an SOI waveguide-based polarization diversity circuit and an InGaAsP-InP gain block. Input light with arbitrary linear polarization state will pass through the gain block twice for a roundtrip ...

A broadband and polarization-insensitive metamaterial absorber

2016 Progress in Electromagnetic Research Symposium (PIERS), 2016
In this work, a broadband and polarization-insensitive absorber with split-ring resonator in the infrared region is proposed. The structure is composed of three layers, in which material of first layer is low-conductivity alloy. The simulated result reveals that the structure can realize a broadband absorption above 90% from 15 THz to 27 THz, which is ...

On the design of polarization-insensitive optoelectronic devices

Semiconductor Science and Technology, 1995
We examine theoretically the problem of the polarization dependence of guided-wave devices. We show that tensile-strained quantum wells near the light-and heavy-hole degeneracy provide almost equal absorption spectra and nearly identical electroabsorption curves in the TE and TM modes, which are necessary features for on-line applications such as ...

Polarization-insensitive nonlinear-optical devices

SPIE Proceedings, 2008
Zincblende semiconductors, such as GaAs, GaP and others, show great potential for quasi-phase-matched nonlinear optical frequency conversion. In addition to broad infrared transparency and high nonlinear coefficient of zincblende materials, the symmetry of their nonlinear optical tensor allows operating nonlinear-optical devices with the following ...
