A Laterally Integrated VCSEL–Electro-Absorption Modulator Enabled by Resonance Detuning and Slow-Light Coupling

Photonics
Directly modulated VCSEL transmitters are widely deployed in short-reach optical interconnects. However, further scaling of per-lane symbol rates in AI/HPC data center fabrics requires modulation schemes beyond the practical limits of direct current ...

VCSELs resurgent

III-Vs Review, 2004
Whatever the viewpoint on the state of play in the telecom/datacom marketplace, it is undeniably the case that the VCSEL is here to stay. Moreover, the potential of this laser diode family is only beginning to be exploited. Much will depend on factors such as materials and device technology, applications and competition in the market from other laser ...
