STITCHING TYPE LARGE APERTURE DEPOLARIZER FOR GAS MONITORING IMAGING SPECTROMETER
Polarization Depolarizer Muller matrix Imaging Spectrometer Stitching Numerical Analysis
2018/5/15
To increase the accuracy of radiation measurement for gas monitoring imaging spectrometer, it is necessary to achieve high levels of depolarization of the incoming beam. The preferred method in space ...
Ultrahigh-contrast and large-bandwidth thermal rectification in near-field electromagnetic thermal transfer between nanoparticles
Ultrahigh-contrast large-bandwidth thermal electromagnetic thermal transfer between nanoparticles
2015/8/7
We exploit the unique properties of optical waves in nanophotonic structures to enhance the capabilities for active control of electromagnetic thermal transfer at nanoscale. We show that the near-@...
Color Breakup Reduction by 180Hz Stencil-FSC Method In Large-Sized Color Filter-Less LCD-TVs
2011/12/16
We proposed the “180Hz Stencil-FSC” method to suppress color break-up (CBU) in field-sequential-color (FSC) LCDs. Applying local color-backlight-dimming technology to FSC- LCDs, a “green-based multi-c...
Compact Polarization-Insensitive Array Isolator Built-in SOA Gate Array Switch Module for Large-Scale Switch Systems
Polarization-Insensitive SOA Gate Array Switch Module Large-Scale Switch Systems
2015/7/15
We developed an SOA gate array switch module with a novel polarization-insensitive built-in array isolator. We achieved excellent optical coupling characteristics that had insertion losses of about 3 ...

2015/8/6
We demonstrate experimentally close to total absorption in monolayer graphene based on critical coupling with guided resonances in transfer printed photonic crystal Fano resonance filters at nea...
160 Gbit/s-200 km Field Transmission Experiment Using a Time-Domain Optical Fourier Transformation Technique with a Large PMD
Time-Domain Optical Fourier Transformation Technique Large PMD
2015/8/4
160 Gbit/s-200 km DPSK field transmission using time-domain optical Fourier transformation was demonstrated with a large PMD. Error-free performance with only a 1.5 dB power penalty was achieved.
Characterizing Discrete and Distributed Scattering of Higher-Order- Modes in Large-Mode-Area Fibres
Characterizing Discrete Distributed Scattering Higher-Order- Modes Large-Mode-Area Fibres
2015/7/30
We characterize higher-order-mode content in large-mode-area fibres using spatially and spectrally resolved mode imaging. The technique is capable of distinguishing between discrete and distributed sc...
