Abstract
An amplified spontaneous emission (ASE) light source and a method for using the ASE light source are provided. The ASE light source may include a seed stage light source for providing a light beam to be amplified. The apparatus may include a tunable element coupled to the seed stage light source configured for filtering a portion of the light beam from the seed stage light source. The apparatus may include a loopback circuit coupled to the tunable element, the loopback circuit comprising a booster stage element for amplifying light from the tunable element.

An amplified spontaneous emission (ASE) light source comprising:
- a seed stage light source for providing a light beam to be amplified;
- a tunable element coupled to the seed stage light source configured for filtering a portion of the light beam from the seed stage light source;
- and
- a loopback circuit coupled to the tunable element, the loopback circuit comprising a booster stage element for amplifying the filtered light beam from the tunable element.
A method for generating light output at an amplified spontaneous emission (ASE) light source, the method comprising:
- generating seed stage light using a medium configured for providing a light beam to be amplified;
- filtering the seed stage light beam at a tunable element configured to filter at least a portion of the seed stage light beam;
- and
- amplifying the filtered light output of the tunable element at a loopback circuit that comprises a booster stage element.
