What is the maximal number of nonoverlapping copies of a regular polyhedron II that can share a common vertex?
Packaged magnetic bubble test circuits made with 4micron period ion-implanted circuits were operated over -55 to +110C.
We investigate efficiency of FWM generation in quasidistributed EDF sections under general power evolution conditions.
We report four-channel discrete multi-tone modulation and detection using silicon photonic circuits.
The emerging communication applications for inter- and intra- data centers demand low-cost and small-from-factor optical transceivers with 100G/400G capacity.
The Skillman system uses combinations of currents of four frequencies, 500, 600, 750 and 900 ~ per sec. for signalling and dialing over junctions and toll lines of any length and complexity.
A previous paper on digital computer simulation of a four-phase d a t a system 1 was concerned with performance in the presence of delay and attenuation distortion, and impulse noise.
A four-sideband stochastic analytical model is developed to investigate the impact of random fluctuations of the zero dispersion wavelength on two pump fiber-optic parametric processes.
We present a concept for colorless tunable optical dispersion compensators consisting of a series arrangement of generalized interferometers and adjustable lenses.
The electrical resistance of a conductor is intimately related to the relaxation of the momentum of charge carriers.
