| Summary: | A semiconductor-based gain equalization device, method and apparatus. In one aspect of the present invention, an apparatus according to an embodiment of the present invention includes a semiconductor material. An optical path is included through the semiconductor material and is optically coupled to receive and transmit an optical beam. The gain equalization device is disposed in the semiconductor material. The optical gain equalization device includes a plurality of Bragg gratings disposed in the semiconductor material optically coupled to receive and transmit the optical beam. Each of the plurality of Bragg gratings have a different Bragg wavelength. The optical beam is to be directed from plurality of Bragg gratings with a non-uniform spectral response to compensate for the spectral non-uniformity of optical amplifiers. |
