Abstract
In some implementations, a device may generate a data set including at least modal gain values and modal loss values for a semiconductor optical amplifier (SOA) slice. The device may determine, based on the data set, respective widths for a plurality of slices of an SOA using an autoregressive model. A width, of the respective widths, for a slice, of the plurality of slices, may be associated with a maximum conversion efficiency achievable for the slice at a given current density. The device may generate information indicating a geometry for the SOA based on the respective widths for the plurality of slices.

A semiconductor optical amplifier (SOA) device, comprising:
- an SOA having a plurality of slices of respective widths,
- wherein a first slice, of the plurality of slices, precedes a second slice, of the plurality of slices, in a light propagation direction,
- wherein a first width of the first slice is associated with a maximum conversion efficiency achievable for the first slice at an input optical power to the first slice and at a given current density, the first width defining an output optical power from the first slice to the second slice, and
- wherein a second width of the second slice is associated with a maximum conversion efficiency achievable for the second slice at an input optical power to the second slice and at the given current density,
- wherein the input optical power to the second slice is the output optical power from the first slice to the second slice.
A semiconductor optical amplifier (SOA) device, comprising:
- an SOA having an input end and an output end in a light propagation direction,
- wherein a section of the SOA, between the input end and the output end, has a taper that gradually increases in width in the light propagation direction, and
- wherein a slope of the taper decreases in the light propagation direction.
An apparatus, comprising:
- a semiconductor optical amplifier (SOA),
- wherein a first slice of the SOA precedes a second slice of the SOA, in a light propagation direction,
- wherein a first width of the first slice is associated with a maximum conversion efficiency achievable for the first slice at an input optical power to the first slice and at a given current density, the first width defining an output optical power from the first slice to the second slice, and
- wherein a second width of the second slice is associated with a maximum conversion efficiency achievable for the second slice at an input optical power to the second slice,
- wherein the input optical power to the second slice is the output optical power from the first slice to the second slice.
