High Speed Characteristics of VCSELs
The high speed characteristics of Vertical Cavity Surface Emitting Lasers (VCSELs) for use in modern high bandwidth fiber optic networks is presented. An equivalent circuit model based on microwave network analyzer S 11 measurements is developed. The dynamic operation of multi-transverse mode VCSELs is also investigated. Experimentally, a laser with two orthogonally polarized modes is examined....
متن کاملHigh-Speed InP-Based Long-Wavelength VCSELs
The rapid growth of internet and cloud computing applications drives a huge demand for bandwidth capacity in communication networks, while power consumption, cost, and space density must scale down. This growth leads to an increase in the size of data centers (longer optical links), and of the fibers’ channel data rate, rooted in Moore’s Law. Until now, multi-mode fibers (MMF) have been largely...
متن کاملDesign and Performance of High-Speed VCSELs
Over the past several years, high-speed vertical-cavity surface-emitting lasers (VCSELs) have been the subject of intensive worldwide research due to their applications in optical interconnects and optical data networks. The performance of VCSELs, especially with respect to their high-speed characteristics, has made significant progress. In this chapter, we first present the basic theory for cu...

متن کاملHigh-efficiency, high-speed VCSELs for optical interconnects
High-efficiency, high-speed, tapered-oxide-apertured vertical-cavity surface-emitting lasers (VCSELs) emitting at 980 nm have been demonstrated. By carefully engineering the tapered oxide aperture, the mode volume can be greatly reduced without adding much optical scattering loss for the device sizes of interest. Consequently, these devices can achieve higher bandwidth at lower current and powe...
