Envelope tracking (ET) power amplifiers and supply modulators represent a pivotal advance in modern radio frequency (RF) design, particularly for wireless communications. These systems dynamically ...
Abstract: Directly modulated lasers (DMLs) are an attractive technology for short-reach intensity modulation and direct detection communication systems. However, their complex nonlinear dynamics make ...
Abstract: A novel 20 GHz 1.55 μm passively colliding-pulse mode-locked AlGaInAs/InP laser was demonstrated with a small RF linewidth (10 kHz), low timing jitter of 218 fs (4-80 MHz) and low divergence ...
