    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: In a pump/probe experiment, information about an event is detected and correlated with an accumulatable quantity representing the elapsed time interval between the arrival of the pump and probe pulses at the experiment. The accumulatable quantity is used to configure the pump and probe sources to eliminate temporal resolution problems caused by pulse timing jitter, the complexity of amplification, continuum generation, and subsequent reamplification, as well as data acquisition rate limitations. Two pulse sources serve as pump and probe pulses respectively. Each pulse is directed at the experiment. A portion of each pump pulse is diverted to a detector before it reaches the experiment, and a portion of each probe pulse is diverted to another detector. The pump and probe pulses are no-coincident in time at the experiment. Quantities related to the time difference and the information imposed on the probe pulse by the experiment are accumulated to obtain data about the temporal evolution of the event.

    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).
