摘要： A monolithic semiconductor device extends primarily along a vertical direction and includes the following layers. A first semiconductor layer and a second semiconductor layer form an active region between them. A third semiconductor layer is doped the same type as the second semiconductor layer but is lattice mismatched to the second semiconductor layer. The lattice mismatch results in unwanted electrical effects. An additional doping layer, preferably a delta doping layer, is located in close proximity to the interface between the second and third semiconductor layers. The delta doping layer mitigates the unwanted electrical effects introduced by the lattice mismatch. In a preferred embodiment, the device further includes a bottom mirror layer and a top mirror layer, which together form a laser cavity including the active region.

摘要： Systems and methods for extending a linear range of a semiconductor optical amplifier (SOA). A feedback layer is included in an SOA. The optical mode of the SOA is distributed between the feedback layer and the active region. As output optical power increases, the mode confinement of the active region increases and the mode is drawn from the feedback layer into the active region. The increase in the mode confinement offsets a loss of material gain such that the linear range of the SOA is extended. In one embodiment, the modal gain increases an higher output optical powers.

摘要： Systems and methods for tuning a DBR stack for an optical amplifier. The DBR layers in a mirror of the optical amplifier have a duty cycle that can be altered to tune a location of a channel drop in a gain spectrum. In addition to changing the duty cycle, the DBR stacks can be segmented. The segmented DBR stacks and/or the selected duty cycle tunes a location of a channel drop outside of a range of wavelengths of interest.
