Carrier injection in the grating section is used to tune the emission wavelength of a single growth step, single frequency, ridge waveguide InGaAs/GaAs quantum well distributed Bragg reflector laser with two top contacts. Single longitudinal mode emission with over 30 dB of sidemode suppression is observed throughout a tuning range of 6 nm with 60 mA of injection current in the grating section. The tuning mechanism for these devices is dominated by current injection heating rather than carrier depression of the refractive index.<<ETX>>
The authors propose and demonstrate the integration of a quantum well intersub-band photodetector (QWIP) and a light emitting diode (LED) for making large two-dimensional focal plane arrays for thermal imaging applications. The newly developed QWIP technology is combined with the well established LED technology both based on GaAs and related epitaxially grown alloys, such as AlGaAs and InGaAs.<<ETX>>
Low-dimensional excitons in general, and quantum-well (QW) excitons in particular, are important for linear and nonlinear semiconductor optics applications. The recent observation of the high binding energy of bulk excitons in gallium nitride samples being the main impetus, we undertake a theoretical work to characterize QW excitons in wurtzite semiconductors. In our formulation, we take into account valence band mixing, strain, and piezoelectric field effects. The in-plane behavior of excitons is treated variationally, whereas the finite-element method is used for the dependence along the growth direction. The formulation is applied to GaN-Al/sub x/ Ga/sub 1-x/N QW's. The presence of the piezoelectric field leads to the well-known quantum-confined Stark effect. We deduce from an oscillator strength analysis that the quantum-confined Franz-Keldysh effect is operational for QW's of width around 45 /spl Aring/ for an aluminum content of x=0.15. Our results further indicate that, for very clean samples, QW excitons should not ionize at room temperature even in the presence of the piezoelectric field for sufficiently narrow QW's. We determine the fractional dimensionality of the QW excitons in the absence of the piezoelectric field, which can in principle be cancelled by introducing delta-doped ionized layers on either side of the QW. The absorption spectra associated with the low-lying 1s excitons are also presented for several well widths.
CW room-temperature lasing in Y-junction semiconductor ring lasers with radii as small as 50 mu m is reported. The dependence of the threshold current density on device dimensions is examined for radii in the range 50-200 mu m and for waveguide widths of 2-8 mu m. From these quantum-well devices, approximately 1 mW of CW single-frequency Te-polarised lasing output is obtained.<<ETX>>
The fabrication and performance of 8 element arrays of asymmetric Fabry-Perot reflective modulators in the InGaAsP material system driven directly from silicon VLSI circuits are reported. These arrays were solder bond hybridised onto CMOS driver circuits for chip level optical interconnect, and have demonstrated contrast ratios of 4.8 dB and reflectivity changes of 22% when driven directly from the CMOS circuit.<<ETX>>
