C O M M E R C I A L transatlantic radio telephone service to Europe was inaugurated on January 7, 1927, using a long-wave circuit on a frequency of 60 kilocycles.
Properties of Pb1 — xSnxTe-PbTe1—ySey lattice-matched single-heterostructure (SH) diode lasers grown on Pb1 — xSnxTe substrates by liquid-phase epitaxy were studied for various compositions in the
PREFACE: Since its invention in 1962, the semiconductor laser has come a long way.
A clear inbound-outbound asymmetry is found in Voyager 1 Low Energy Charged Particle (LECP) phase space densities near 6 R(J).
Locally reducing the width of a wide photonic crystal (PhC) waveguide generates a constriction which acts as an internal reflector.
HE classical exact treatments of the modes of propagation of elastic waves in isotropic media having stress-free surfaces b u t extending indefinitely in at least one dimension are those of Rayleig
The propagation of a quasi-single-cycle terahertz pulse through an active terahertz quantum cascade laser is studied.
In optical communication systems operating near the zero-dispersion wavelength of the fiber, the wavelength of semiconductor lasers should remain stabilized to minimize the effects of fiber disper
Performance troubleshooting is notoriously difficult for distributed microservices-based applications.
