Electrical injection lasers emitting in the 1.3 mu m wavelength regime based on (GaIn)As/Ga(AsSb)/(GaIn) As type-II double "W"-quantum well heterostructures grown on GaAs substrate are demonstrated. The structure is designed by applying a fully micro

Nonlinear rovibrational polarization response of water vapor to ultrashort long-wave infrared pulses
We study the rovibrational polarization response of water vapor using a fully correlated optical Bloch equation approach employing data from the HITRAN database. For a 10-mu m long-wave infrared pulse the resulting linear response is negative, with a

Vertical external cavity surface emitting lasers are ideal testbeds for studying nonlinear many-body systems driven far from equilibrium. The classical laser gain picture fails, however, when a high peak intensity optical pulse of duration shorter th

A systematic study of microscopic many-body dynamics is used to analyze a strategy for how to generate ultrashort mode locked pulses in the vertical external-cavity surface-emitting lasers with a saturable absorber mirror. The field propagation is si

We simulate and elucidate the self-channeling of high-power 10 mu m infrared pulses in atomic gases. The major new result is that the peak intensity can remain remarkably stable over many Rayleigh ranges. This arises from the balance between the self

Using optical pump-white light probe spectroscopy, the gain dynamics is investigated for a vertical-external-cavity surface-emitting laser chip, which is based on a type-II heterostructure. The active region of the chip consists of a GaAs/(GaIn) As/G

A series of (Ga, In)As/GaAs/Ga(As, Sb) multi-quantum well heterostructures is analyzed using temperature-and power-dependent photoluminescence (PL) spectroscopy. Pronounced PL variations with sample temperature are observed and analyzed using microsc
