POLARIZATION-INDEPENDENT FIELD-INDUCED ABSORPTION-COEFFICIENT VARIATION SPECTRUM IN AN INGAAS/INP TENSILE-STRAINED QUANTUM-WELL

We report the absorption-coefficient variation of a tensile-strained InGaAs/InP quantum well measured throughout the spectral range near and away from the band gap. We discuss the spectral absorption-coefficient variation spectra of an unstrained, a 0.15%, a 0.30% a 0.45% tensile-strained quantum well and show that the difference between the wavelengths of absorption-coefficient variation peak for TE and TM modes becomes zero with 0.3% tensile strain. We will also show that this wavelength difference varies linearly with the magnitude of the strain.
