Grating coupled photonic crystal demultiplexer with integrated detectors on InP-membrane [PDF]

, 2008
We report on the successful integration of grating fiber couplers, compact photonic crystal demultiplexers and efficient p-i-n photodetectors on a single bonded InP-membrane chip.

High Efficiency Polarization-Independent Slanted Grating for RGB Bands

IEEE Photonics Journal, 2021
We proposed a slanted grating suitable for RGB bands which is polarization-independent and has a high diffraction efficiency of −1st order under normal incidence.

Multichannel operation of an integrated acousto-optic wavelength routing switch for WDM systems [PDF]

, 1994
Polarization independent acousto-optic tunable filters (PIAOTF's) can operate as transparent wavelength-selective crossconnects to route signals in wavelength division multiplexed optical networks.

Generation of Polarization Independent Ring-Airy Beam Based on Metasurface

Photonics
In this paper, we generated polarization-independent ring-Airy beams by designing metasurfaces that can realize modulations of both phase and amplitude. In numerical simulation, such metasurfaces are designed by placing subwavelength rectangular slits in

Dual-band, double-negative, polarization-independent metamaterial for the visible spectrum

, 2012
We present the first dual-band negative index metamaterial that operates in the visible spectrum. The optimized four-functional-layer metamaterial structure exhibits the first double-negative (i.e., simultaneously negative permittivity and permeability ...

PBS-Free Polarization-Independent PON Coherent Receiver [PDF]

IEEE Photonics Technology Letters, 2020
We introduce a coherent receiver that, without DSP and/or polarization coding at the transmitter, requires no Polarization Beam Splitter and still is polarization-independent. It is experimentally demonstrated at 10 Gbit/s with a sensitivity of −37.6 dBm at FEC level.

A high-speed tunable beam splitter for feed-forward photonic quantum information processing

, 2012
We realize quantum gates for path qubits with a high-speed, polarization-independent and tunable beam splitter. Two electro-optical modulators act in a Mach-Zehnder interferometer as high-speed phase shifters and rapidly tune its splitting ratio. We test

Polarization Independent Achromatic Meta-Lens Designed for the Terahertz Domain

Frontiers in Physics, 2020
In recent years, metasurface-based focusing elements have gradually become an indispensable type of terahertz lenses. However, the meta-lens often suffers from chromatic aberration due to the intrinsic dispersion of each element, especially in the ...

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Spatially and polarization resolved plasmon mediated transmission through continuous metal films [PDF]

, 2009
The experimental demonstration and characterization is made of the plasmon-mediated resonant transmission through an embedded undulated continuous thin metal film under normal incidence.
