Despite recent progress in electronic structure engineering of type-II materials for mid-infrared lasers, suppression of Auger recombination at room temperature has been limited. We present an active region design, consisting of AlAsSb/InAs/GaInSb/In

We describe temporally and spectrally resolved measurements of the material differential gain, differential refractive index, and linewidth enhancement factor for a multilayer superlattice intended for use in midwave-infrared semiconductor lasers. We

Temperature and density-dependent Auger recombination rates are determined for a four-layer broken-gap superlattice designed for suppression of both Auger recombination and intersubband absorption. The structure is intended as the active region of bo

Several midwave-infrared (MWIR) lasers have been demonstrated, including 2.8-, 3.1-, 3.2-, 3.4-, 4.1-, and 4.3-/spl mu/m diodes. The devices utilize multiple-quantum-well (MQW) active regions in which the quantum wells (QW's) consist of InAs-GaInSb b

A procedure for optimizing MQW hetero-nipi waveguide phase modulators is presented that includes both drive voltage and frequency response. Experimental phase change, absorption change, and frequency response measurements of a modulator designed usin

We report the growth optimization of multiple quantum well and modulator samples containing InAs/GaAs short-period strained-layer superlattice (SPSLS) well using our advanced digitized reflection high-energy electron diffraction (RHEED) system. Modul

The in‐well ambipolar diffusion coefficients and carrier lifetimes in ordered all‐binary quantum wells, composed of (InAs)2(GaAs)5 short‐period strained‐layer superlattices (SPSLSs) grown on [001]‐oriented GaAs substrates, are measured usin

In‐plane transport in an InAs/GaAs semiconductor hetero‐n‐i‐p‐i has been investigated using picosecond transient grating techniques and an order‐of‐magnitude enhancement of the ambipolar transport relative to that measured in a similar

The nonlinear optical properties of a n‐i‐p‐i structure containing strained superlattice quantum wells in the intrinsic regions are studied using picosecond pump and probe pulses of the same photon energy. For pump fluences as low as 1.1 μJ/cm
