EVALUATION OF GAAS/AL0.3GA0.7AS MULTIPLE-QUANTUM-WELL WAVE-GUIDES FOR PULSED SQUEEZED-LIGHT GENERATION
We have measured the nonlinear refractive index n2 and two-photon absorption coefficient in GaAs/Al0.3Ga0.7As multiple-quantum-well waveguides in the band tail region about 45 meV below the n=1 heavy hole exciton absorption line. At 883 nm we find that =1.9×10-8 cm W-1 and that n2-1×10-12 cm2 W-1. T...

| description | We have measured the nonlinear refractive index n2 and two-photon absorption coefficient in GaAs/Al0.3Ga0.7As multiple-quantum-well waveguides in the band tail region about 45 meV below the n=1 heavy hole exciton absorption line. At 883 nm we find that =1.9×10-8 cm W-1 and that n2-1×10-12 cm2 W-1. The linear loss coefficient is measured to be 6.3 cm-1 at the same wavelength. Based on these values, we estimate that up to 4.5 dB pulsed squeezing is possible. © 1994 The American Physical Society. |
