The frequency of an InGaAsP DFB laser has been locked to the 2 sub p10 - 3d sub s transition of Krypton atoms at 1.5339 microns using the optogalvanic effect.

A description of a crystal controlled, reactor-valve modulated f.m. transmitter of conventional design. The unit can provide r.f. output powers of 1, 3, 10, 20 or 50 kW in the range 88-108 Mc/s.

Frequency-Modulation: Theory of the Feedback Receiving Circuit By JOHN R. CARSON T H I S paper m a y be regarded both as a continuation of a prior one by the writer and Thornton C.

We demonstrate a novel measurement technique that uniquely identifies the power spectral densities of signal, signal-signal-beat interference, and noise in direct-detection receivers.

Mode-locking of single-section Fabry-Pérot lasers based on InAs/InP quantum dashes is studied by second-harmonic generation frequency-resolved optical gating (SHG-FROG).

This paper describes and demonstrates a full-field (amplitude and phase) optical waveform measurement technique which utilizes interferometry, frequency-to-time mapping, and four-quadrature coheren

The thermal management of electronics is becoming an increasing concern as industry continues to simultaneously push performance while shrinking the size of electronic devices.

Multi-user full duplex (FDX) transmission is instrumental to provide sufficient coverage and reach for the multi-gigabit data rates targeted by MGfast.
