TL;DR: In this article, an increased resonance frequency and reduced damping of the resonance peak leading to a record high modulation bandwidth of 30GHz were observed in 1.55 mm InGaAsP DBR lasers.

TL;DR: This article focuses on IM/DD transmissions, and provides an overview of recent research and development efforts on key enabling technologies for 200 Gbps per lane and beyond, and expects high-speed IM/ DD systems will remain advantageous in terms of system cost, power consumption, and footprint for short reach applications in the short- to mid- term perspective.

TL;DR: In this article, the authors investigated the occurrence of a second resonance frequency in distributed Bragg reflector laser diodes and the high modulation bandwidth resulting from it, and showed that a similar behavior can be obtained in laser Diodes with a passive, low-loss, and gratingless external cavity.

TL;DR: In this article, a comprehensive experimental evaluation of the microwave modulation characteristics of high-speed oxide-confined vertical cavity surface emitting lasers (VCSELs) emitting at 840 nm was performed.

TL;DR: In this paper, a novel type of longitudinal instability due to spatial hole burning in symmetric semiconductor laser structures (DFB lasers in particular) is examined analytically and numerically.
