摘要	A device to monitor light output from a light source, including a V-groove substrate with a reflective coating deposited on at least one surface, an optical fiber, a light source positioned so that an amount of the light emitted, which is less than 100%, enters the optical fiber, a light intensity or source detector positioned so that at least some of the light emitted from the light source, that did not enter the optical fiber impinges upon the light intensity detector, and feedback circuitry. A method of producing a device including the steps of coating a surface of a V-groove substrate with a reflective material, placing a light source in said V-groove substrate. A method of producing a device comprising the steps of coating a surface of a V-groove substrate with a reflective material, placing a light source in said V-groove substrate, placing a light intensity detector in said V-groove substrate, and placing a wave guide structure in said V-groove substrate wherein said reflective material, said light source, said detector and said wave guide structure are positioned in said V-groove substrate so that an amount of light emitted from said light source, which is less than 100%, enters said wave guide structure; and at least some of the light emitted from said light source, that did not enter said wave guide structure reflects from said reflective material and impinges upon said light intensity detector.
其他摘要	一种监视光源光输出的装置，包括具有沉积在至少一个表面上的反射涂层的V形槽基板，光纤，光源，其定位使得发射的光量小于100 ％，进入光纤，光强度或光源检测器，其定位使得从光源发出的至少一些未进入光纤的光照射在光强度检测器和反馈电路上。一种制造器件的方法，包括用反射材料涂覆V形槽衬底的表面，将光源放置在所述V形槽衬底中的步骤。一种制造器件的方法，包括以下步骤：用反射材料涂覆V形槽衬底的表面，将光源放置在所述V形槽衬底中，将光强度检测器放置在所述V形槽衬底中，以及放置在所述V形槽基板中的波导结构，其中所述反射材料，所述光源，所述检测器和所述波导结构位于所述V形槽基板中，使得从所述光源发出的光量小于100 ％，进入所述波导结构;从所述光源发出的至少一些未进入所述波导结构的光从所述反射材料反射并照射在所述光强度检测器上。
主权项	A device to monitor light output from a light source, comprising: a substantially V-groove assembly comprising a first and a second substrate, wherein said second substrate extends outwardly beyond the surface of said first substrate, and wherein said second substrate has a reflective coating deposited thereon; a wave guide structure positioned in said V-groove assembly; a light source positioned in communication with said wave guide structure and positioned so that an amount of light emitted from said light source, which is less than 100%, enters said wave guide structure; and a light detector positioned so that at least some of the light emitted from said light source, that did not enter said wave guide structure impinges upon the light detector.
