Characterization of an integrated DFB-SOA laser for photonic systems
Abstract
We study the optical properties of a monolithically integrated distributed feedback laser and semiconductor optical amplifier (DFB-SOA) laser structure designed to overcome limitations of DFB lasers in producing high optical powers. We find that this laser structure possesses numerous unique and interesting qualities such as independent power and wavelength control, low RIN, narrow linewidth with the SOA section influencing the linewidth. The device is then employed in communication system testbeds demonstrating that it can meet optical source requirements for both direct detection and coherent photonics systems.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
