Advanced modeling and simulation tools are being developed and applied to a wide range of semiconductor materials and devices, especially for the infrared. Device classes of current interest include (1) interband cascade and quantum cascade lasers for the mid-wave infrared, (2) infrared nonlinear frequency combs based on high-Q microresonators, (3) nanophotonic processes enabled by plasmon and phonon polariton modes in deeply subwavelength resonators, and (4) nanophotonic optical traps for ultracold atoms. We are also pursung work on type-II superlattice photodetectors for the mid- and long-wave infrared and solar cells, and thermophotovoltaic devices incorporating narrow-gap semiconductors.
Novel material systems under investigation include arsenide, phosphide, and antimonide quantum heterostructures; HgCdTe and narrow-gap III-V infrared detector materials; and infrared diode laser structures. In-house custom-built software to perform multi-band k.p, tight-binding, effective-bond orbital, and empirical pseudopotential bandstructure calculations is available. Other in-house software packages include those for comprehensive modeling of interband cascade lasers, quantum cascade lasers, photodetectors, and solar cells. Access to general-purpose multiphysics modeling software COMSOL and commercial electromagnetic finite-difference code (Lumerical) is also available.
