    Notes:
    Reflectance experiments on GaAs/Ga1−xAlxAs single quantum well structures were performed at 4.2 K, with different thicknesses of the front GaAlAs barrier layer (100–1000 A(ring)). The observed exciton reflectance line shapes depend strongly on the thickness of the front barrier layer due to the interferences between the reflected waves from the front surface and the quantum well interfaces. Calculations of the reflectance line shapes show good agreement with the observations. The absorption coefficient for the electron heavy-hole exciton transition in a single quantum well sample is determined. Our study also provides a new understanding of the line shapes measured in photoreflectance experiments.

    Notes:
    Photoreflectance experiments with magnetic fields up to 14.5 T are performed on epitaxial GaAs and GaAs/Ga1−xAlxAs quantum well samples at room temperature and 2 K. Our experiments show unique and direct evidence that photoreflectance structures are excitonic transitions in all of the above cases.

    Notes:
    Optical absorption and photoluminescence measurements were made on Cd0.9Mn0.1Te doped with As, P, Cu, and Au. Shallow acceptor ionization energies were determined as: 108 meV for P; 115 meV for As; 170 meV for Cu; and 180 meV for Au. These energies are larger than those for CdTe due to the formation of bound magnetic polarons. Self-consistent numerical calculations of the bound magnetic polarons are made for As and P dopants. The absorption spectra below 0.5 eV were separated into contributions from acceptor photoionization, inter- and intraband transitions, and free-hole absorption. Acceptor concentrations in the 1017 cm−3 range were found for As and P doping; however, Cu and Au were found to produce high compensation (〈1012 cm−3). Mechanisms for this behavior are discussed.

    Notes:
    A versatile and compact fiber-optic system for Raman scattering and photoluminescence is described. This optical fiber system was used for inelastic light-scattering experiments at temperatures down to T=0.35 K and dc magnetic fields to B=30 T. We believe this is the first observation of Raman scattering in either of these environments, both of which are normally inaccessible with optical Dewars. The portable head has a 1-cm o.d. and permits measurements longitudinal and transverse to the applied magnetic field. Observation of spin-flip Raman scattering from donor bound magnetic polarons in (Cd, Mn)Se demonstrates this system at the extremes of both magnetic field and temperature.

    Notes:
    A simple fiber-optic system for optical spectroscopy is demonstrated. It allows experiments to be performed at low temperatures without an optical Dewar. This low-cost apparatus is useful for a variety of optical experiments such as photoluminescence, reflectivity, and absorption, in addition to polarization measurements such as Faraday rotation. The main feature is an all-glass system made from commercially available fiber-optic cables and glass rods, and contains no focusing optics. Small diameter (〈1 cm) sample holders are constructed that fit conveniently into storage Dewars or small diameter Dewars for high-field magnets. Large diameter (few mm) flexible fiber bundles permit efficient coupling to inexpensive light emitting diode (LED) sources and to fiber-optic illuminators. Fiber-optic measurements of photoluminescence in Cd1-xMnxTe, x=0.1, at high magnetic fields is illustrated.

    Notes:
    An optoelectronic effect based on Faraday or Kerr rotation and the quantum-confined Stark shift is demonstrated. It is novel in that the degree of rotation is controlled by an electric field as opposed to a magnetic field. By applying an electric field to a quantum well structure, the Faraday rotation can be tuned into resonance, thereby varying the rotation angle of plane polarized light. We have observed a resonant rotation of 10° in GaAs at a magnetic field of 1 T. By applying a gate voltage of 2 V to a GaAs/AlGaAs superlattice structure, we observed a change in rotation of 1.3° at 2 K. The Faraday–Stark effect could be useful in electrically controlled light switches and high-speed optical modulators. © 1996 American Institute of Physics.

    Notes:
    Two-photon absorption spectra of GaAs were obtained using photoconductivity techniques. At zero magnetic field, the spectrum has a photon energy ((h-dash-bar)ω) dependence of (2(h-dash-bar)ω–Eg)3/2 just above the energy band gap (Eg), and can be described without considering exciton enhancement effects. Oscillatory behavior in the photoconductive response at zero field as a function of incident two-photon energy has been observed and shown to be due to the interaction of the photoexcited electrons and longitudinal optical phonons. At high magnetic fields, the spectra are quantitatively interpreted in terms of a modified Pidgeon–Brown energy band model.
