Abstract
A wavelength selective light source is disclosed. The wavelength selective light source comprises a broadband light source producing light having a plurality of wavelengths and a demultiplexer that receives the light and separates at least one of the plurality of wavelengths from said light. Further, a multiplexer is included for coupling the at least one of said plurality of wavelengths into an output waveguide. Finally, a semiconductor optical amplifier is provided that receives the at least one of the plurality of wavelengths from the output waveguide and amplifies the at least one of the plurality of wavelengths.

A wavelength selective light source comprising:
- a broadband light source producing light having a plurality of wavelengths;
- a demultiplexer that receives the light and separates at least one of said plurality of wavelengths from said light;
- a multiplexer for coupling said at least one of said plurality of wavelengths into an output waveguide;
- a semiconductor optical amplifier that receives said at least one of said plurality of wavelengths from said output waveguide, said semiconductor optical amplifier amplifying said at least one of said plurality of wavelengths and outputting an amplified output signal.
A method for outputting an optical signal of a selected wavelength comprising:
- providing a broadband light source that outputs light having a plurality of wavelengths, including said selected wavelength;
- demultiplexing said light using a demultiplexer to extract said selected wavelength;
- and
- amplifying said selected wavelength into an optical signal.
A wavelength selective light source comprising:
- a broadband light source producing light having a plurality of wavelengths;
- a demultiplexer that receives the light and separates at least one of said plurality of wavelengths from said light, wherein said demultiplexer comprises:
- (a) an input waveguide for carrying the light from said broadband light source;
- (b) a plurality of intersecting waveguides intersecting with said input waveguide to form a plurality of intersections;
- and
- (c) a plurality of switches disposed on said plurality of intersections;
- a multiplexer for coupling said at least one of said plurality of wavelengths into an output waveguide;
- and
- a semiconductor optical amplifier that receives said at least one of said plurality of wavelengths from said output waveguide, said semiconductor optical amplifier amplifying said at least one of said plurality of wavelengths and outputting an amplified output signal.
