摘要： A method continuously monitors variations in the size of particles present in a fluid on a real time basis. The method includes passing one or more optical signal through the fluid such as engine oil. The variation (attenuation or enhancement) in the intensity of the optical signal is continuously measured with respect to time. In an embodiment, the method enables monitoring of the amount, size and onset of particle agglomeration using single or multiple wavelengths as interrogating optical signal(s). An exemplary embodiment is provided for monitoring of the amount, size and onset of soot particle agglomeration in engine oil using single or multiple wavelengths as interrogating optical signal(s).

摘要： A method of writing a waveguide using an ultrashort laser beam is disclosed. The laser beam is directed to a substrate in transverse relation to a waveguide propagation axis to generate an ultrashort laser pulse focus in the substrate. A refractive index is modified in an affected region in the substrate along the waveguide propagation axis via the ultrashort laser pulse focus, and the ultrashort laser pulse focus is moved in a direction other than the waveguide propagation axis to generate a widened affected region along the waveguide propagation axis. The widened affected region has a cross-sectional profile capable of supporting a fundamental mode of a signal having a telecommunications infrared (TIR) wavelength, while the affected region has a cross-sectional profile incapable of supporting the fundamental mode of the signal having the TIR wavelength.

摘要： Disclosed herein are an optical device, such as a connector or mode enlarger, and a method of fabricating the device. The disclosed device includes an optical medium having a first face for, e.g., permanent attachment to a waveguide, a second face for, e.g., a non-permanent connection, and a region between the first and second faces. A non-fiber, connector waveguide is disposed in the region to propagate the single-mode signal from the first face to the second face. The connector waveguide is optically matched to the waveguide at the first face to receive the single-mode signal carried by the waveguide. The connector waveguide includes a taper section such that the connector waveguide is enlarged at the second face to support an expanded beam of the single-mode signal for propagation through the non-permanent connection. In some cases, the taper section receives the single-mode signal from an input section of the connector waveguide to generate an expanded or narrowed beam of the single-mode signal via discrete modulation of waveguide cross-section. An output section of the connector waveguide then supports the propagation of the expanded or narrowed beam of the single-mode signal through the non-permanent connection.
摘要翻译：本文公开了诸如连接器或模式放大器的光学装置以及制造该装置的方法。所公开的装置包括光学介质，其具有用于例如永久地附接到波导的第一面，用于例如非永久性连接的第二面以及第一和第二面之间的区域。非光纤连接器波导设置在该区域中以将单模信号从第一面传播到第二面。连接器波导在第一面处与波导光学匹配以接收波导承载的单模信号。连接器波导包括锥形部分，使得连接器波导在第二面处被放大，以支持用于通过非永久连接传播的单模信号的扩展光束。在一些情况下，锥形部分从连接器波导的输入部分接收单模信号，以通过波导横截面的离散调制产生单模信号的扩展或变窄的波束。连接器波导的输出部分然后通过非永久性连接来支持单模信号的扩展或变窄的波束的传播。
