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： A method of using a beam of ultra-short laser pulses, having pulse durations below 10 picoseconds, to adjust an optical characteristic within an optical medium is provided. The beams would have an intensity above a threshold for altering the index of refraction of a portion of the optical medium. The beams could be selectively applied to the optical medium and any structures formed or existing therein. Thus, the beam could be moved within a waveguide in the optical medium to alter the index of refraction of the waveguide forming any number of different longitudinal index of refraction profiles. The beam could also be moved within the optical medium near the waveguide to alter an effective index of refraction of a signal traveling within the waveguide. The techniques described can be used to improve, alter or correct performance of waveguide-based optical devices, such as arrayed waveguide gratings and cascaded planar waveguide interferometers.

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.

The apparatus comprises of a body 105, at least one fluidic cavity 110 to capture a fluid sample, at least one light source 115 to emit an optical signal and at least one optical detector 120 to detect the optical signal. The fluid sample is collected continuously from a path of a fluid flow and multiple optical properties are measured in real time to determine the condition of the fluid. The apparatus is installed in-line with the path of the fluid flow in the system for which the fluid is being used and monitored. The apparatus avoids environmental contamination and wastage of the fluid sample by returning the fluid sample back into the fluid flow.
