High speed directly modulated single mode lasers are becoming important optical components for short reach communication. In order to cover a transmission distance that is required for passive optical network and inter data-center applications, the chirp managed laser is an attractive transmitter technology. This technology enables to use a directly modulated laser for longer reach systems, resulting...
Heterogeneously integrated DFB lasers, consisting of thin InP membranes coupled to low loss Si wire waveguides possess several advantages compared to traditional all-InP DFB lasers. The thin membranes give a large optical confinement factor and their small surface area results in relatively small parasitic capacitances. Both properties make these lasers very well suited for high speed direct modulation...
