Dual-wavelength Quantum Cascade (QC) lasers with heterogeneous cascades are presented.

Dual-wavelength Quantum Cascade (QC) lasers with heterogeneous cascades are presented.

ADIO telephone circuits are now in regular use between New York and London, New York and Buenos Aires, San Francisco and Honolulu, and many other points.

Due to the joint evolution of mobile applications and cloud services, mobile users routinely act as both content consumers and producers.

This article describes a basic building block for microwave waveguide filters. It uses a new coupling scheme where all resonant modes are used at their cutoff frequency.

For short distances of 150-200 miles multi-channel carrier systems are not, in general, economical, as their adjustment and maintenance is relatively complicated.

Optical and electronic properties of In sub x Ga sub (1-x) As strained layer superlattices grown on InP have been investigated over the entire range of Indium composition, 0 x 1.

Type II noncritically phase matched sum frequency generation by mixing of the 1.319micron and 1.338micron lines of a Q-switched Nd: YAG laser with their second harmonics is demonstrated.

The Type O carrier is an economical short-haul carrier system especially suitable for use under 150 miles.
