High-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...

متن کاملHigh-speed optical interconnects with 850nm VCSELS and advanced modulation formats
We present our recent work on high-speed optical interconnects with advanced modulation formats and directly modulated 850 nm VCSELs. Data transmission at nearly 100 Gbps was achieved with 4-PAM. Forward error correction, equalization and preemphasis are also explored. The system aspects of the advanced modulation formats and their impact on the VCSEL requirements are discussed. Requirements on...
متن کاملHigh Speed, High Capacity Bused Interconnects using Optical Slab Waveguides
In this paper we consider the use of optical slab waveguides as buses in a parallel computing environment. We show that slab buses can connect to many more elements than conventional electrical or ber optic buses. We also introduce a novel multiplexing scheme called mode division multiplexing that vastly increases the number of independent channels that a single slab can support. We show that o...
متن کاملHigh 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....
