Abstract
Disclosed is a hybrid broadband optical source comprising an amplified spontaneous emission (ASE) light source module to generate ASE, a gain medium to amplify the ASE, a pump light source to generate pump light, and a wavelength selective coupler to supply the pump light to the gain medium.
Claims7
A hybrid broadband optical source comprising:
- an amplified spontaneous emission (ASE) light source module to generate ASE and having a first isolator integrated at the output end thereof;
- a gain medium to amplify the ASE;
- a pump light source to generate pump light;
- and
- a wavelength selective coupler to supply the pump light to the gain medium, wherein the first isolator is configured to pass the ASE inputted into the first isolator and block light progressing in the opposite direction.
