Broadband polarization correction with programmable liquid-crystal modulator arrays.

چکیده
We demonstrate a novel method of parallel, multiwavelength state-of-polarization (SOP) correction. Using a new liquid-crystal modulator array design, we are able to rotate the distorted input SOP spectrum to a fixed linear state on a wavelength-by-wavelength basis. We report experimental correction of up to 25.5-dB polarization-dependent loss over a 13-nm bandwidth around 1550 nm.

Characterization of programmable phase modulator with polarization quadrature interferometer By Zhenrong Wang The purpose of this master project is to characterize the Programmable Phase Modulator (PPM) made by Hamamatsu Photonics and use it as a deformable mirror to test the principles of Multi-Conjugate Adaptive Optics (MCAO) in a real-time Adaptive Optics (AO) system testbed with Polarizatio...
متن کاملProgrammable polarization-independent spectral phase compensation and pulse shaping by use of a single-layer liquid-crystal modulator.
What we believe to be the first use of a single-layer liquid-crystal modulator array for spectral phase pulse shaping that operates independently of input polarization is reported. Polarization insensitivity is essential to optical-fiber-based applications such as dispersion compensation.

We report the first use of a double-layer liquid crystal modulator array for spectral phase pulse shaping that operates independent of polarization. Such insensitivity to polarization is crucial for fiber applications, e.g., dispersion compensation.
متن کاملBroadband Phase Modulating System for White-Light Fourier Transformations
We discuss a white-light processing system that produces a dynamic, achromatic Fourier transformation over the visible spectrum. The system includes an achromatic Fourier transform lens system and a lowdispersion spatial light modulator. A programmable phase mask can only write patterns with a spatial frequency appropriate for one wavelength. However, this problem is resolved by scaling broadba...
متن کاملPulse shaping of incoherent light by use of a liquid-crystal modulator array.
We demonstrate the use of a femtosecond pulse-shaping apparatus for electronically programmable phase filtering of amplified spontaneous emission from an erbium-doped fiber amplifier. Pulse shaping applied to a broadband incoherent light (noise) input results in reshaped noise, with a specially tailored electric field correlation function. Our experiments clearly reveal that phase filtering can...
