tailoring a high Transmission Fiber probe for photon scanning tunneling microscope
Applied Physics Letters, 1996Co-Authors: Toshiharu Saiki, S Mononobe, Motoichi Ohtsu, Nobuo Saito, Jun Ichi KusanoAbstract:Transmission efficiency of a Fiber probe used in photon scanning tunneling microscope is evaluated as a function of aperture diameter. The apertured probe has been fabricated by chemical etching technique and metal coating. By comparing two types of probes with different cone angles, we determine the most influential factor in the Transmission property of the metal‐cladding tapered waveguide. A long tip with high efficiency is developed by a multistep etching method so as to be suitable during actual scanning operation. Photoluminescence imaging of lateral p‐n junctions on the GaAs substrate is demonstrated in the illumination‐collection hybrid mode operation of photon scanning tunneling microscope.

Enhanced Submarine Transmission Fiber Enabling Novel Dispersion Maps and Improved System Performance
IEEE Photonics Technology Letters, 2011Co-Authors: G. Mohs, W. T. Anderson, A. Pilipetskii, E.a. GolovchenkoAbstract:We present ultra-long-haul Transmission experiments using an enhanced conventional Fiber with - 14-ps/nm/km dispersion coefficient. This new Fiber allows for novel dispersion maps with improved Transmission performance compared to dispersion maps based on nonslope matched submarine Fiber, and similar performance to dispersion flattened maps.

Crosstalk in WDM systems caused by cross-phase modulation in erbium-doped Fiber amplifiers
IEEE Photonics Technology Letters, 1998Co-Authors: Mark Shtaif, M. Eiselt, Robert W. Tkach, R.h. Stolen, A.h. GnauckAbstract:We show experimentally that cross-phase modulation (XPM) in erbium-doped Fiber amplifiers (EDFAs) may cause crosstalk between channels transmitted over conventional Fiber. As this effect is constant over a large range of wavelength separations, it is capable of creating interference between a large number of channels. In some important cases, XPM originating in the EDF may become comparable in significance to that originating in the Transmission Fiber.

High-sensitivity two-stage erbium-doped Fiber preamplifier at 10 Gb/s
IEEE Photonics Technology Letters, 1992Co-Authors: R.i. Laming, A.h. Gnauck, C.r. Giles, M.n. Zervas, D.n. PayneAbstract:An optical preamplifier with a record sensitivity of -38.8 dBm (102 photons/bit) at 10 Gb/s has been demonstrated. When the amplifier is employed in a practical link without an input isolator, the sensitivity is only slightly degraded to -37.6 dBm (135 photons/bit) by input coupling losses and feedback due to Rayleigh backscattering in the Transmission Fiber. It is predicted that this penalty can be reduced to 0.15 dB with an improved isolator in the composite EDFA.
