We report a polarization insensitive broadband semiconductor optical amplifier design based on an asymmetric multi-quantum well structure. The device operates with 9 dBm saturation output power, 23 dB gain, and <0.8 dB polarization dependency.
We report a polarization insensitive broadband semiconductor optical amplifier design based on an asymmetric multi-quantum well structure. The device operates with 9 dBm saturation output power, 23 dB gain, and ≪0.8 dB polarization dependency.
A broadband semiconductor optical amplifier (SOA) has been realized for the coarse WDM (CWDM) based systems operating over the O-band range. The SOA exhibits low polarization sensitivity, 23 dB gain and low noise based on the asymmetric multi-quantum well (AMQW) technique. Reflective SOAs (for modulating the upstream data in passive optical networks (PONs)) as well as in-line or booster amplifiers...
In this paper, we used a topology gradient method coupled with a finite element method in order to optimize the shape of a microstrip component. We appended a 2D distribution of metal on the substrate and tried to optimize its form by taking benefits of the topology gradient method. The concept of topology gradient using a numerical method is given in this article, and finally, the results of using...
