Polarization-independent Talbot effect
Optics Letters, 2015We report the first observation of polarization-independent Talbot effect with a high-density grating for TE and TM polarizations, which is attributed to the identical phases and diffraction efficiencies of the diffraction orders for both polarizations.

Polarization-Independent Electrooptic Depolarizer
Integrated Photonics Research, 1995Optical depolarizers are frequently used in optical measurement equipment as well as in fiberoptic sensors to remove undesired polarization sensitivity [1]. Recently, depolarizers have also been employed in long-haul all-optical communication systems to avoid polarization hole burning (anisotropic gain saturation) in the erbium-doped fiber amplifiers ...

Polarization-Independent Optical Injection Locking
Optical Fiber Communication Conference, 2017A pluggable system making optical injection locking independent of the incoming signal's polarization-state is proposed and experimentally verified to maintain stable locking for random polarizations without performance loss in carrier recovery for coherent optical communications.

Compact polarization-independent optical circulator
Applied Optics, 1981This paper introduces a compact polarization-independent optical circulator for communications using multimode optical fibers. This circulator consists of two pairs of rutile prisms used as polarization separators, a YIG Faraday rotator, a ring-shaped magnet, and a quartz halfwave plate.

Broadband and polarization-independent waveguide-fiber coupling
Silicon Photonics XVIII, 2023Waveguide-to-fiber coupling is one of the key challenges in silicon photonics. Many approaches have already been experimentally demonstrated, such as grating couplers, inverse tapers, sub-wavelength structures, lensed fibers, photonic wire bonds, small-core fibers and separate waveguide interposers.

Ultra-compact polarization-independent 3 dB power splitter in silicon
Conference on Lasers and Electro-Optics, 2021We experimentally demonstrate a polarization-independent 3 dB power splitter (PIPS) assisted with subwavelength structure. The device possesses ultra-compact (1.2 µm × 2.62 µm) and polarization-independent features with an operating bandwidth over 50 nm (

Polarization-independent tunable reflector
2014 16th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM), 2014In this paper, a novel tunable reflector with gain medium was designed, fabricated and measured. By incorporating active elements into two magnetic metamaterial SRRs, gain medium with positive loss, perfect losslessness and even negative loss can be tuned to switch the function of the active reflector among a perfect absorber, a perfect reflector and a
