Broadband wavelength conversions using broadband SOAs

LEOS 2001. 14th Annual Meeting of the IEEE Lasers and Electro-Optics Society (Cat. No.01CH37242), 2002
Future wavelength-division-multiplexed (WDM) networks using a large number of wavelengths will need wavelength conversions between those wavelengths. Broadband wavelength conversions between 1300 nm and 1550 nm represent a milestone of such a capability.

Broadband photophoretic spectroscopy

Optics Letters, 1980
A means for obtaining broadband photophoretic spectra is described. The sensitivity of the technique is found in accordance with radiometric theory to increase markedly with pressure reduction below 1 atm. Noise oscillation induced by radiometric torques is contained through the use of electronic damping.

CATV broadband technologies

Proceedings EC-VIP-MC 2003. 4th EURASIP Conference focused on Video/Image Processing and Multimedia Communications (IEEE Cat. No.03EX667), 2004
Cable television systems can be successfully used as broadband multimedia networks. Cable TV providers can offer additional services over CATV network, such as Internet access, video on demand and other applications. The article describes different techniques and technologies applied in modern two-way interactive CATV systems that enable variety of new

Broadband spin echoes and broadband SIFTER in EPR

Journal of Magnetic Resonance, 2015
Applications of broadband pulses for EPR have been reported for FID, echo detection and inversion pulses recently. Here we present a broadband Hahn, stimulated and refocused echo sequence derived from adiabatic pulses. The formation of echoes is accomplished by using variable chirp rates and pulse lengths.

Broadband Birefringent Metainterfaces

Conference on Lasers and Electro-Optics 2012, 2012
We report broadband birefringent metainterfaces comprising 2D arrays of phased optical antennas that can create light beams with arbitrary polarization states and arbitrary propagation directions over a wide spectral range (from λ=5 to 14 μm).

Broadband attosecond pulse shaping

2007 Quantum Electronics and Laser Science Conference, 2007
We use semiconductor (Si) and metallic (Al, Zr) transmission filters to shape, in amplitude and phase, high-order harmonics generated from the interaction of an intense titanium sapphire laser field with a pulsed neon gas target. Depending on the properties of the filter, the emitted attosecond pulses can be optimized in bandwidth and/or pulse length ...

Is broadband land seismic as good as marine broadband?

SEG Technical Program Expanded Abstracts 2013, 2013
To evaluate the potential of modern land seismic capabilities and further improve the seismic value for the mining industry, AngloGold Ashanti (AGA) has acquired a prospect area of 35 km2. The geological objective of this test is to image the formations above and below the Ventersdorp Control Reef (VCR) and down to the carbon leader reef, for depths ...
