摘要	One or more single mode waveguide devices are fiber coupled such that signals to an optical element affect the coupling of the waveguide device to an optical fiber. A number of systems and methods are disclosed to adjust the coupling of the waveguide device to the optical fiber. These include dithering the tunable optical element at different frequencies along differing axes and using a lock-in technique to derive an error signal for each degree of motion, using a beamsplitter to form a secondary image of the focused beam on a position-sensitive detector, the use of a chiseled fiber to generate reflections from the angled facets, using an additional laser for a secondary image, or obtaining a secondary image from an angled fiber or a parasitic reflection.
其他摘要	一个或多个单模波导器件是光纤耦合的，使得到光学元件的信号影响波导器件与光纤的耦合。公开了许多系统和方法来调整波导器件与光纤的耦合。这些包括沿不同轴以不同频率抖动可调谐光学元件，并使用锁定技术导出每个运动程度的误差信号，使用分束器在位置敏感探测器上形成聚焦光束的次级图像，使用凿刻的光纤从成角度的小平面产生反射，使用附加的激光用于次级图像，或者从成角度的光纤或寄生反射获得次级图像。
主权项	An optical transmission method comprising: selecting a laser from an array of lasers on a semiconductor substrate, each laser in the array emitting light at a wavelength different than other lasers in the array of lasers; establishing an optical path from the selected laser to an optical output, such that light from the selected laser is transmitted into an optical output; providing some of the light from the selected laser to a plurality of detectors; comparing signals indicative of light incident on at least some of the plurality of detectors; and adjusting the optical path based on the comparison of the signals.
