Abstract
A relative intensity noise (RIN)-suppressed light source is provided that includes a light source that produces an incoming light. A semiconductor optical amplifier (SOA) arrangement receives the incoming light and provides a significant reduction in the RIN as its output. The SOA arrangement includes one or more SOAs in saturation that behave like a high pass filter for the amplitude of the incoming light.

A relative intensity noise (RIN)-suppressed light source comprising:
- a light source that produces an incoming light;
- and
- a semiconductor optical amplifier (SOA) arrangement that receives the incoming light and provides a significant reduction in the RIN as its output, the cascaded SOA arrangement includes one or more SOAs in saturation that behave like a high pass filter for the amplitude of the incoming light.
A method of performing relative intensity noise (RIN) suppression comprising:
- providing a light source that produces an incoming light;
- and
- receiving the incoming light using a semiconductor optical amplifier (SOA) arrangement that provides a significant reduction in the RIN as its output, the SOA cascaded arrangement includes one or more SOAs in saturation that behave like a high pass filter for the amplitude of the incoming light.
