Higher speed VCSELs by photon lifetime reduction

, 2011
The impedance characteristics and the effects of photon lifetime reduction on the performance of high-speed 850 nm VCSELs are investigated. Through S 11 measurements and equivalent circuit modeling we show that the parasitic mesa capacitance can be ...

1060 nm VCSELs for long-reach optical interconnects [PDF]

, 2018
Reach extension of high capacity optical interconnects based on vertical-cavity surface-emitting lasers (VCSELs) and multimode fibers (MMFs), as needed for large-scale data centers, would benefit from high-speed GaAs-based VCSELs at 1060 nm.

Quantum noise in VCSELs

, 2000
In this paper, we study in detail the intensity noise characteristics of vertical-cavity surface-emitting lasers (VCSELs). We demonstrate the possibility of generating intensity squeezed light with free-running or injection-locked VCSELs.

Adaptive coupling approach for single mode VCSELs with polymer waveguides

, 2014
A novel coupling approach for single mode VCSELs and planar optical waveguides is presented. The coupling is based on the embedding of the VCSELs inside the substrate and the adaptive fabrication of waveguides on ...
