Abstract:
1. A fiber-grating semiconductor laser with tunability comprising: a substrate for having the first section for accommodating a semiconductor laser diode and the second section for accommodating an optical fiber, a semiconductor laser diode for being placed on the first section of the substrate; and an optical fiber being placed on the second section of the substrate, being coupled optically with an output facet of the semiconductor laser diode and including a Bragg grating, wherein the Bragg grating of the optical fiber is compressed or elongated to vary the wavelength of the output light of the fiber-grating semiconductor laser diode, wherein the second section has a line path, to divide the substrate portion and the line path portion, the line path portion is movable within the reach of the line path and includes a body separated from the substrate by a certain gap, wherein the substrate and the body corresponding to the second section have the first line groove and the second line groove facing the output facet of the semiconductor laser diode, to accommodate the optical fiber, and the Bragg grating of the optical fiber is compressed or elongated as the body moves.
