We present measurements of the dependence of the phase-conjugate reflectivity on signal frequency for Brillouinenhanced four-wave mixing at pump intensities above the threshold instability. The measurements were made in TiC1(4) at lambda = 1 microm a

We have investigated the nonlinear optical properties of a new class of strained-layer superlattices, the intrinsic Stark effect superlattices (ISES). The superlattices consisted of GaInAs/GaAs grown along the (211) B direction. We observed a shift o

We present electrooptic modulation results on [100], [211]A and [211]B oriented InGaAs/GaAs multiple quantum wells. Internal electric fields are generated by a combination of strain, due to lattice mismatch, and the piezoelectric properties of III‐

The nonlinear optical properties of a new class of strained‐layer superlattices (intrinsic Stark effect superlattices) have been investigated. Specifically, we have compared the nonlinear transmission of Ga1−xInxAs‐GaAs strained‐layer superla

The threshold for instability in Brillouin-enhanced four-wave mixing has been experimentally determined as a function of both the phase mismatch and the ratio of the pump beam intensities and is shown to agree with theoretical modeling. The effective

Amplification of a weak input signal (~0.5 pJ) in a high-gain (G = 109) Brillouin amplifier has resulted in an output signal-to-noise ratio of 85:1, within a factor of 4 of the theoretical estimate. For a near-diffraction-limited Gaussian pump beam t

High-repetition-rate generation of up to 325 mJ of Raman amplified radiation near 615 cm-1 has been demonstrated in CO2-pumped para-H2 using a low-power, microwave-shifted CF4 laser as an input Stokes seed source. Experiments were limited to 200 Hz,
