High-speed wavelength selectable optical source and method thereof

A high-speed wavelength selectable optical source comprising:

• an optical source that generates a light having at least two or more wavelengths;
• a demultiplexer that separates the light by wavelength and outputs lights having separated wavelengths;
• and
• an optical switch that selects a light having a wavelength selected among the separated wavelengths from the demultiplexer and outputs the selected light having the selected wavelength to the optical source to cause injection locking.

A high-speed wavelength selectable optical source comprising:

• a first optical source that generates a light having a predetermined wavelength;
• a second optical source that generates a light having at least two or more wavelengths comprising the predetermined wavelength;
• a demultiplexer that separates the light from the first optical source by wavelength;
• and
• an optical switch that selects the predetermined wavelength selected among the separated wavelengths from the demultiplexer and outputs a light having the predetermined wavelength to the second optical source to cause injection locking.

A high-speed wavelength selectable optical source comprising:

• an optical amplifier that outputs a light having at least two or more wavelengths and amplifies an incident light with a predetermined gain;
• a reflective filter unit comprising at least one reflective filter that reflects a light having a predetermined wavelength;
• and
• an optical switch that outputs the light from the optical amplifier to a selected reflective filter, and inputs the reflected light from the selected reflective filter to the optical amplifier.
