    The first results obtained using a SOI device for microdosimetry applications are presented. Microbeam and broadbeam spectroscopy methods are used for determining minority carrier lifetime and radiation damage constants. A spectroscopy model is presented which includes the majority of effects that impact spectral resolution. Charge collection statistics were found to substantially affect spectral resolution. Lateral diffusion effects significantly complicate charge collection

    A novel technique for the fabrication of birefringent splittable composite (BISPEC) fiber is reported. We describe in details the design consideration, practical fabrication, and characterization of this fiber. The distinctive feature of this fiber is that the principal axes of the constituent fibers can be accurately aligned in the preform stage so that long lengths of well-aligned fiber can be drawn. We further demonstrate the application of this fiber by fabricating a polarization-maintaining coupler by simply introducing a local taper. Measurements show that such a coupler can have polarization extinction ratio as large as 31 dB (in the best case)
