摘要： The invention describes the method and apparatus for enhanced efficiency in a laterally-coupled distributed feedback (LC-DFB) laser. In a device featuring the effective ridge design, lateral confinement of the guided optical modes is provided by a surface etched grating, which also serves as a DFB element of the laser. Coupling and quantum efficiency of such a LC-DFB laser both improve with an increase of the lateral mode order. In accordance with this invention, a dramatic enhancement of the laser efficiency is achievable by designing it to operate in one of the higher order modes, notably the first order mode, while all the other lateral modes, including the zero order mode, are suppressed through gain-loss discrimination. In the exemplary embodiment of the invention, this enhanced efficiency technique is applied to the design of a single-mode LC-DFB laser suitable for a monolithic integration with other active and passive functional elements of photonic integrated circuits fabricated by using one-step epitaxial growth.

摘要： A method of using a robot to repeatedly manipulate a brazing nozzle is provided. In a preferred embodiment, the method includes using a pointer to teach the robot to manipulate the brazing nozzle at a preselected angle with respect to, and length away from, an instant surface along a multi-dimensional seam line on an automotive sheet metal body. The pointer includes a base portion for connection with an end of a robot arm. The pointer additionally has a main body having a length inclusive of the base portion approximating the length of the brazing nozzle and the preselected work distance of the brazing nozzle away from the work piece. A contact portion of the pointer is continuous with the main body and is provided for contacting the work piece. The contact portion has two small parallel-spaced surface flats. The surface flats of the contact portion are generally aligned in a common plane at a preselected angle with respect to the robot arm. The flats allow the programming of the robot to follow a multi-dimensional path which is generally parallel with respect to the seam line. After programming, the brazing nozzle is connected with the robot arm and is manipulated to braze the automotive body in lines generally parallel-spaced from the seam line or diagonally between lines parallel-spaced from the seam line.
