Directly modulated semiconductor lasers represent a crucial technology in modern optical communications, where the injection current is directly varied to encode information onto the laser output.

Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users to ...

High-speed analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) typically are characterized using continuous wave (CW) signals. There are several reasons for this practice: 1) ...
