Polarization-independent optical circulator: an experiment
Applied Optics, 1980Many kinds of optical devices are being researched in various countries for application in optical fiber communication. Some devices have polarization-dependent characteristics that cause a decrease in the coupling efficiency of the optical fibers.

Birefringent polarization-independent beam splitter
Applied Optics, 1979By adjusting both the thickness and angle of the incidence of a birefringent channeled spectrum plate, the extraordinary and ordinary reflectivities can be equalized, thereby providing a polarization-independent beam splitter.

Polarization Effects in Polarization-Independent and Polarization Maintaining Fiber Amplifiers
2006 Digest of the LEOS Summer Topical Meetings, 2006Polarization effects in fiber optical amplifiers are described. Theoretical and experimental results for the statistical variation of the polarization extinction ratio (PER) in a PM amplifier are presented. PER variation between units and over temperature is analyzed.

Polarization Independent GaAs/AlGaAs Electrooptic Modulator
Proceedings of IEE/LEOS Summer Topical Meetings: Integrated Optoelectronics, 1996Two designs for polarization independent GaAs-AlGaAs interferometric electrooptic modulators are described. One design uses the linear electrooptic effect to couple degenerate TE/TM eigenmodes of a single-mode waveguide. In the other design the eigenmodes need only be near degenerate.

Polarization-independent beam splitter
Review of Scientific Instruments, 1983We report a new type of beam splitter capable of producing a division of light in a polarization-independent manner. Most off-axis beam splitters have a pronounced polarization dependence. An experimental device with a splitting ratio of about 7 dB varied less than ±0.1 dB as a function of incident linear polarization.

Polarization-Independent Black-Phosphorus Polarizer in Visible Regime
IEEE Photonics Technology Letters, 2017We propose black-phosphorous (BP) TE- and TM-pass polarizers whose polarization state can be controlled using strong in-plane anisotropic property of BP. The tunable polarizer is configured as a BP-SiO2 metamaterial waveguide to take advantage of the change in refractive index of the whole structure. TE and TM-pass polarizers can be achieved with small

Polarization independent metasurface energy harvester
2016 IEEE 17th Annual Wireless and Microwave Technology Conference (WAMICON), 2016We present a polarization independent metasurface electromagnetic energy harvester. A new metasurface harvester is composed of an ensemble of 8 × 8 electrically-small resonators arranged periodically on a Rogers substrate. The harvester is designed in such a way that the maximum power transfer occurs at 2.6 GHz. The proposed harvester has a low profile,

Polarization‐independent planar amplifier array
Microwave and Optical Technology Letters, 1999A method of amplifying a signal with any polarization using an active microstrip patch reflectarray is presented. A 12-element X-band polarization-independent reflection amplifier is then developed to demonstrate the operation of this type of array. Gain, axial ration, and radiation patterns for this array are presented.© 1999 John Wiley & Sons, Inc.

A polarization-independent grating resonator
IEEE Journal of Quantum Electronics, 1997A polarization-independent optical resonator based on a novel phase-shifted grating structure is proposed and analyzed. Its application as a polarization-independent optical wavelength filter with ultranarrow bandwidth and fine tunability is described.
