An ultrafast all-optical asymmetric Fabry-Pérot switch based on bulk Be-doped InGaAsP grown by He-plasma-assisted epitaxy
We demonstrated ultrafast all-optical switching, using an asymmetric Fabry-Pérot device, based on bulk Be-doped InGaAsP grown by He-plasma-assisted molecular beam epitaxy. We achieved 5 ps switching window (1/...

Characterization of InGaAs/InP Epitaxial Layers Grown Over V-Groove Patterned InP Substrates using Gas Source Molecular Beam Epitaxy
Gas source molecular beam epitaxy has been used to deposit single InP layers, and multiple layers of InGaAs/InP over V-groove patterned (100) InP substrates. The V-grooves were defined by the (211)A and (111)B...
