ABSTRACT:
A semiconductor laser source having a laser diode and a fiber Bragg grating is described. The laser diode has first and second facets from which output light is emitted. A first end of the fiber Bragg grating is located near the second facet to receive output light from the laser diode. The fiber Bragg grating has a very narrow linewidth about a selected wavelength and reflects output light in the selected narrow linewidth back into the laser diode through its second facet. The output light emitted from the first facet has a very narrow linewidth about the selected linewidth.
