摘要： A method and apparatus for adjusting the path of an optical beam and in particular, a method and apparatus for improving the coupling efficiency (power input) of free-space radiation into an optical waveguide using, as part of an optical train, a weak lens positioned along the path of the optical beam (the Z axis) and adapted to adjust the path of the beam. The weak lens is translatable along the Z axis and also along at least one axis perpendicular to the Z axis (the X or Y axes). In a preferred embodiment, the weak lens possesses all three positional degrees of freedom (i.e., it is adjustable along all of the X, Y, and Z axes). In certain preferred embodiments, the weak lens is also capable of one or even two orientational degrees of freedom (i.e., pitch and/or yaw).

摘要： A harmonic frequency conversion module is disclosed including a polarization maintaining (PM) fiber optical link for providing an output stabilized from power fluctuation by the inclusion of one or more polarizers in the PM fiber optical link. Removing polarization distortions removes noise which has a significant negative effect on the output of harmonic frequency conversion elements. It has been found that the noise in frequency converted light has additional components, caused by mode interaction during conversion. In accordance with the present invention, we are able to remove the spikes in this noise, making it more stable and less dependent on external conditions. If the PM optical fiber route consists of multiple elements creating polarization distortions, a polarizer should be inserted between the most distorting element and the output of the fiber system. If many elements contribute to polarization distortions, several polarizers can be inserted into the system.

摘要： A periodically poled optical waveguide comprising a nonlinear optical crystalline material is provided having poled optical domains slanted with respect to direction of propagation of light within the waveguide. Light reflected from slanted poled optical domains does not couple efficiently back into the optical waveguide, which facilitates reduction of backreflection towards a semiconductor laser source coupled to the waveguide. Reduction of backreflections facilitates stable operation of the semiconductor laser source. A method of manufacturing of a periodically poled optical waveguide with slanted poled domains is also provided.
摘要翻译：提供包括非线性光学晶体材料的周期性极化的光波导，其具有相对于波导内的光的传播方向倾斜的极化光畴。从倾斜的极化光畴反射的光不能有效地耦合回到光波导中，这有助于将反向反射减少到耦合到波导的半导体激光源。反向反射的减少有助于半导体激光源的稳定操作。还提供了具有倾斜极化畴的周期性极化光波导的制造方法。

摘要： A method for monitoring laser light launched into a core of a single mode fiber includes launching a portion of light directly into the cladding about the core. The cladding launched light is a known fraction of the core launched light and can be monitored by placing a detector about the cladding. Detected light including light that was launched into the cladding and has leaked through the cladding is used as a known fraction of light in the core and can be used to control the laser light source. This can be done with a straight section of single mode optical fiber and does not require bending the fiber. Advantageously, most of the core launched light remains in the core as guided light.
