    Notes: Photonic crystal waveguides including resonant cavities have been fabricated and investigated by transmission spectroscopy. The waveguides consist of two missing rows in a triangular lattice of air holes in a GaAs/AlGaAs slab–waveguide structure. The mirrors of the cavities are formed by adding two rows of holes perpendicular to the guiding direction inside the waveguide. The spectrally broad photoluminescence of an InAs quantum dot layer in the heterostructure is used to probe the transmission. Depending on the resonator size, characteristic resonant peaks are observed in the transmission spectra. Finite difference time domain calculations of the transmission of the investigated structures show good agreement with experimental data. © 2002 American Institute of Physics.

    Enhanced transmission through photonic-crystal-based bent waveguides by bend engineering (2001)

    Notes: We have studied the transmission of light through two-dimensional photonic-crystal-based waveguides with two 60° bends. The waveguides consist of three or five missing rows of holes inside a triangular photonic crystal block fabricated on an AlGaAs/GaAs waveguide structure. Fine tuning of the bend design results in a severe impact on the transmission behavior, leading to losses as low as 1.1 dB/bend. Measurements of losses in the bends were performed by a comparison with a straight guide of identical length. © 2001 American Institute of Physics.

    Single-mode operation of coupled-cavity lasers based on two-dimensional photonic crystals (2001)
    Woodbury, NY : American Institute of Physics (AIP)

    Notes: We report the fabrication of short-cavity lasers with highly reflective two-dimensional photonic crystal mirrors on an InGaAsP/InP laser structure emitting at 1.57 μm. An intracavity photonic crystal mirror creates two coupled cavities, which provide additional longitudinal mode selection for stable single-mode operation with side-mode suppression ratios exceeding 35 dB. The shortest lasers with l=100 μm overall length have a threshold current of 13 mA and provide more than 4 mW power under continuous wave operation. Longer devices with l=200 μm deliver up to 9 mW. A maximum modulation bandwidth of 7.9 GHz was determined by relative intensity noise measurements. © 2001 American Institute of Physics.

    Quantum point contacts fabricated by nanoimprint lithography (2000)

    Notes: The potential of integrating nanoimprint lithography into electronic device fabrication is demonstrated by means of a quantum point contact (QPC). A Si-mold with a split-gate pattern is embossed into a thin polymer film located on top of a modulation-doped GaAs/AlGaAs heterostructure. The split-gates are fabricated by metal evaporation and lift-off. The gate tip separation ranges from 180 nm to 400 nm. Transport studies performed at a temperature of 4.2 K show conductance quantization with varying gate voltages. © 2000 American Institute of Physics.
