We have investigated two In1−xGaxAsyP1−y/InP p-i-n multiple quantum well (MQW) solar cell structures (with and without gold contacts) with intrinsic (i)-InP spacers and two InP p-i-n control samples (with and without gold contacts) using electror

We describe a 4 by 4 array of embedded control two input, one output optoelectronic switching nodes based on the field effect transistor self electro-optic effect device (FET-SEED) technology. The arrays have electrical fan-out to remove the loss ass

We present the design, fabrication, and demonstration of a 10/spl times/10 matrix-addressed vertical-cavity top-surface-emitting laser (VCSEL) array. These arrays are batch-fabricated from full 3-in diameter GaAs/AlGaAs wafers. We show that no perfor

Sequential resonant tunneling is proposed to enhance the photocurrent and reduce recombination losses in photovoltaic devices based on multiple-quantum-well (MQW) heterostructures. An InGaAsP/InP MQW p–i–n diode with built-in sequential resonant

We report the observation of bistable polarization switching in a vertical‐cavity surface‐emitting laser under optical injection. The wavelength dependence of the switching is measured. It is found that this polarization switching is achieved thr

We demonstrate record high pulsed output power exceeding 530 mW from an electrically pumped phase‐coupled 8×8 vertical cavity surface emitting laser array (SELA) at room temperature. Three array types are compared: an 8×8 pixellated SELA(PSELA),

We describe symmetric self‐electro‐optic effect devices (S‐SEEDs) with clamping diodes connected to the center node of the devices to ensure both diodes of the S‐SEEDs have an electric field across them at all times. These diode‐clamped S
