摘要： An apparatus selectively transmits light in one of two orthogonal polarizations in an optical fiber. The apparatus has a facing surface formed at one location on the fiber to expose the evanescent field of an optical signal in the fiber. A nematic liquid crystal is placed in contact with the facing surface so that it is in communication with the evanescent field of the optical signal. The nematic crystals have a first orientation state which presents a first refractive index to light traveling in one polarization and a second refractive index to light traveling in the other polarization. The light traveling in one polarization is well guided while the light traveling in the other polarization is radiated at the facing surface. Thus, only light of one polarization continues to propagate through the fiber. The nematic crystals have a second orientation state in which the relative refractive indices for the two polarizations of light are changed so that the polarization which was originally well guided is radiated at the facing surface and the polarization which was originally radiated is well guided. The change in the orientation states of the nematic crystals is accomplished by applying an electric field between two electrodes so that the nematic crystals align themselves with the electric field.
摘要翻译：一种装置选择性地透射光纤中的两个正交偏振中的一个中的光。该装置具有在光纤上的一个位置处形成的面对表面，以暴露光纤中光信号的消逝场。向列液晶被放置成与相对表面接触，使得其与光信号的渐逝场相通。向列型晶体具有第一取向状态，其对于以一种偏振行进的光和对另一种偏振光行进的光呈现第二折射率的第一折射率。在一个极化中行进的光被良好地引导，而在另一个极化中行进的光在相对表面处被辐射。因此，只有一个极化的光继续传播通过光纤。向列型晶体具有第二取向状态，其中光的两个偏振的相对折射率改变，使得最初被良好导向的偏振辐射在相对表面，并且最初辐射的偏振被良好地引导。向列结晶的取向状态的变化通过在两个电极之间施加电场来实现，使得向列晶体与电场对准。

摘要： An optical fiber laser includes a single-mode optical fiber doped with a lasing material such as Neodymium. The optical fiber is pumped with a pump optical signal having a pump wavelength selected to cause spontaneous emission of an optical signal at a second wavelength different from the pump wavelength. The optical fiber is formed into a laser cavity such as by including a suitable reflector at each of the two ends of a suitable length of the optical fiber so that the emitted optical signal oscillates therein. One of the reflectors has a reflectivity at the wavelength of the emitted light so that most (e.g., approximately 95%) of the emitted light is reflected back into the laser cavity and a smaller portion (e.g, approximately 5%) is transmitted through the mirror as a laser output signal. Alternatively, the optical fiber can be formed into a ring laser structure using an optical coupler that couples a substantial portion (e.g., approximately 95%) of the emitted light back into the ring for recirculation therein and provides a smaller portion of the emitted light (e.g., approximately 5%) as a laser output signal. The wavelength of the pump optical signal is selected to be outside the pump variable tuning range of the Neodymium-doped optical fiber (i.e., the range of pump wavelengths which stimulate emitted wavelengths having a average wavelengths with a generally one-to-one correspondence to the pump wavelength). Pumping with a pump signal outside the pump variable tuning ranges causes the emitted light to have a broad spectral envelope of longitudinal modes having emission wavelengths corresponding to substantially all the pump variable tuning range. Thus, by pumping the optical fiber with a single pump wavelength, a broadband laser output signal is generated.

摘要： A superfluorescent broadband fiber laser source comprises a fiber doped with laser material coupled to a multiplexing coupler. In the preferred embodiment, a source of pumping illumination provides pumping light to the doped fiber, and the coupler is adjusted to have a 0% coupling efficiency at the wavelength of the source. The pumping light is sufficiently intense to produce amplified spontaneous emission within the doped fiber, and gives rise to a forward signal and a backward signal. One of the superfluorescent signals is reflected back to the doped fiber by a reflector cemented to one end of the doped fiber or to one end of another fiber through the coupling function of the coupler. The coupler is adjusted to provide complete coupling at the frequency of the lasing light. The temperature dependence of the coupler can be selected to reduce or cancel the temperature dependence of the superfluorescent signal. Other arrangements utilizing the multiplexing properties of the coupler are also described. An all-fiber reflector can also be used.

摘要： Efficient immutable syntax representation with parent pointers under incremental change is enabled by creating a data structure comprising at least one tree structure that allows both upward and downward references in the tree and a tree structure that is immutable (read-only), and allows parts of itself to be re-used in other data structures. The data structure described enables tools to search and target particular sub trees. The fragment of the tree representing the targeted sub tree is produced as it is used. The rest of the tree is not produced. The read-only tree retains relative information, allowing it to be reassembled and shared.

摘要： When writing code, data structures that include inferred symbols are created based on usage of undefined symbols. As the user continues writing code, code model can be updated to represent updated information based on a learning model. Data structures including inferred symbols can be used by software development tools to provide developer help for symbols that are not yet created or are not yet bound. Inferred symbols can be visually distinguishable making the appearance of the inferred symbol information differ from actual symbol information. The appearance of information based on inferred symbols can be included within tools by activating a particular mode in a programming environment. Conversion of the inferred symbol to a real symbol may trigger the automatic compiler-generation of additional source code by a background compiler. Inferred symbols may be converted to actual symbols by activation of an option to make an inferred symbol a real symbol.

摘要： A consume-first mode for an editor is automatically entered if one or more predefined heuristic conditions are met. Some examples of heuristic conditions include conditions indicating that a user will be entering computer program source code during test-driven development, user action to undo autocompletion, and expected entry of a dynamically typed item identifier. In addition to heuristic consume-first mode, some editors recognize an explicit command to enter or exit the consume-first mode. A list of completion suggestions may be displayed in the consume-first mode, but autocompletion is turned off. An identifier may also be preemptively included on a suggested completions list for use before a user has entered that identifier using the editor.
