Photorefractive polymer composite operating at the optical communication wavelength of 1550 nm
(Georgia Institute of Technology, 2004-11)
A photorefractive polymer composite sensitized at 1550 nm through direct two-photon absorption has been developed. We show an external diffraction efficiency of 3% in four-wave-mixing experiments and perform holographic ...
High-performance photorefractive polymer operating at 1550 nm with near-video-rate response time
(Georgia Institute of Technology, 2005-10)
The development of a high-performance photorefractive polymer composite operating at 1550 nm is reported. We show 40% internal diffraction efficiency with response time of 35 ms and a net gain of 20 cm ⁻¹ in four-wave ...
Ultrafast-pulse diagnostic using third-order frequency-resolved optical gating in organic films
(Georgia Institute of Technology, 2004-10)
We report on the diagnostic of ultrafast pulses by frequency-resolved optical gating (FROG) based on strong third-harmonic generation (THG) in amorphous organic thin films. The high THG conversion efficiency of these films ...
Video-rate compatible photorefractive polymers with stable dynamic properties under continuous operation
(Georgia Institute of Technology, 2004-09)
We report on photorefractive polymer composites that exhibit stable dynamic properties under continuous operation. These materials are based on a bis-triarylamine side-chain polymer matrix with a low ionization potential. ...
High-performance photorefractive polymer operating at 975 nm
(Georgia Institute of Technology, 2004-08)
A family of photorefractive polymer composites has been developed that enable high-performance device operation at a wavelength of 975 nm. This constitutes a major extension into the near-infrared spectral region for the ...
