    Large (50 μm)2 metal–semiconductor–metal photodetectors with 18 GHz bandwidth at 3 V bias; Reduction of hole pileup (1998)

    Notes: Metal–semiconductor–metal photodetectors were fabricated on an AlGaAs/GaAs/AlGaAs double heterostructure with no graded layers. Devices with photolithographically defined finger spacing and width of 1 μm ("1×1") exhibited a saturation bandwidth of greater than 20 GHz, for bias voltages between 3 and 4 V. We attribute this to minimal hole pileup, and propose a simple model for the energy of hot holes near the band offset at the cathode. Using this model, estimates of the bias required to reduce hole pileup in different material systems were derived. The model shows good agreement with results reported here and elsewhere. © 1998 American Institute of Physics.

    Notes: [Auszug] I have made a rudimentary effort .to explore the effect using a noise display generated by passing the green (514 nm) beam of an argon-ion laser through a pair of ground glass plates, one of which could be translated at a controlled speed. The speckle pattern so generated was projected on a screen. ...

    Loss coefficients for blazed waveguide corrugations (1977)

    Optical and quantum electronics 9 (1977), S. 249-258

    Notes: Abstract The coupling between bound modes of a corrugated dielectric-slab waveguide and modes of the radiation continuum is analysed by a perturbation method. Loss coefficients that account for the power coupled into radiation modes by any Bragg order of corrugations with an arbitrary profile are determined for the bound modes. Agreement is found with published results for sinusoidal profiles. The proportion of power coupled out through each dielectric interface of the slab waveguide is also determined. When the corrugation has an asymmetric (blazed) profile and coupling to radiation modes is by the first Bragg order, more power can be coupled out through one interface than the other, even if the refractive indices of the cladding regions are equal. If the coupling is by a higher Bragg order, then the division of power can be considerably more unequal than for first-order coupling, with the greater proportion leaving the side of the waveguide opposite to that for first-order coupling. The ratio of the power coupled out the two sides varies cyclically with radiation wavelength.

    Broadband matrix switches: Electro-optic or optoelectronic? (1986)
    Springer
    Optical and quantum electronics 18 (1986), S. 273-277

    ISSN: 1572-817X

    Topics: Electrical Engineering, Measurement and Control Technology , Physics
    Notes: Abstract Photonic matrix switches using optical (directional coupler) and optoelectronic (photoconductor) principles are compared. It is concluded that, although broadband switching performance can be about equivalent for the individual devices, the optoelectronic matrix offers significant advantages in several important applications, particularly for large-scale broadband switching.
