    摘要： A novel narrow linewidth laser device is disclosed that includes a gain element, such as a quantum well, quantum dot or bulk waveguide laser chip and a fiber Bragg grating formed in an optical fiber positioned to receive the output from a first end of the gain element and return a portion of said output back into the gain element. The fiber Bragg grating is constructed so that its power reflectivity profile has a ratio of reflectivity slope over reflectivity at the 3 dB point below the reflectivity peak on the red side (longer wavelength side) of the grating larger than a value of 2/nm. The operating wavelength of the device may be tuned thermally, electrically, or thermo-electrically to be on the red side of the fiber Bragg grating reflectivity profile, preferably, but not necessarily, at the 3 dB point below the reflectivity peak or lower. In another embodiment, a second grating is optically coupled to a second end of the gain element and has a reflectivity profile that overlaps at least a portion of the reflectivity profile of the front end fiber Bragg grating.

    摘要： A novel narrow linewidth laser device is disclosed that is formed monolithically on a semiconductor substrate, such as an indium phosphide substrate, that includes a continuous waveguide with a gain section and a grating section wherein a grating is constructed so that its power reflectivity profile has a ratio of reflectivity slope over reflectivity at the 3 dB point below the reflectivity peak on the red side (longer wavelength side) of the grating larger than a value of 2/nm. The operating wavelength of the device may be tuned thermally, electrically, or thermo-electrically to be on the red side of the fiber Bragg grating reflectivity profile, preferably at the 3 dB point below the reflectivity peak or lower. In another embodiment, a second grating is formed on a second grating section of the waveguide on the opposite side of the gain section than the first grating section and wherein the reflectivity profile of the second grating overlaps at least a portion of the reflectivity profile of the first grating.

    摘要： A novel free space optics transceiver is disclosed comprising at least one light source, at least one photodetector, corresponding positioning means that can independently adjust the position of the light source and the photodetector, and a controller that can send and receive alignment frames conforming to a communications protocol to and from a remote optical transceiver and can use information in the incoming alignment frames from the remote optical transceiver to appropriately adjust the position of the light source and the photodetector thereby maximizing the received power of light signals sent by the remote optical transceiver. Also, an alignment method is disclosed wherein the controller continuously adjusts the positions of the light source and the photodetector until a light signal is acquired from a remote optical transceiver. Then, the incoming alignment information is used to adjust the light source position to achieve bi-directional communication with the remote optical transceiver.
