Optical communications system with semiconductor optical amplifier for link loss correction

A system comprising a first optical communications terminal having:

• a sensor arranged in a receive path of the first optical communications terminal;
• an optical phased array architecture in a receive path of the first optical communications terminal;
• a first semiconductor optical amplifier (SOA) arranged in a transmit path of the first optical communications terminal and configured to adjust an outgoing optical communications signal according to information included in a first incoming optical communications signal;
• and
• a second SOA arranged in the receive path of the first optical communications terminal and configured to adjust a second incoming optical communications signal according to power of the first incoming optical communications signal at the sensor.

A method comprising:

• receiving a first incoming optical communications signal at a sensor via a receive path of a first optical communications terminal;
• adjusting an outgoing optical communications signal using a first semiconductor optical amplifier (SOA) arranged in a transmit path of the first optical communications terminal, wherein the adjusting is according to power of the first incoming optical communications signal at the sensor;
• and
• adjusting a second incoming optical communications signal using a second SOA arranged in the receive path of the first optical communications terminal, wherein the adjusting is according to power of the first incoming optical communications signal at the sensor.
