Quantum-cascade lasers operating above 20 mum (at lambda similar to 21.5 mum and lambda similar to 24 mum) wavelength are reported.
Summary form only given. We report the first QC laser operating above 20 μm, in particular at a maximum wavelength of 21.5 μm.
The large Faraday rotations of Mn-containing diluted magnetic semiconductors has led to their consideration for use in magnetooptical isolators.
In all wireless systems, the first operation that must take place at the receiver is the acquisition of the carrier and timing.
Efficient subband structures that aim at fast adaptation of fractionally spaced equaliser, 0;SF), by exploiting the `prewhitening' effect that a subband decomposition h;is on the spectral dynamics
We propose an adaptive control scheme, based on the least mean squares algorithm, for electronic equalization of polarization mode dispersion.
We propose a fast-adapted subspace tracking algorithm for background subtraction in video surveillance.
A new fast algorithm for the remote sensing image progressive compression was proposed.
The best currently known algorithm for evaluating the Riemann zeta function integral(sigma+it), with a sigma bounded and t large to moderate accuracy (within plus t-c for some c > 0, say) is bas
Real-time periodic transmission across packet switched networks requires clock recovery at the destination. The stochastic nature of packet traffic makes clock recovery difficult.
