摘要：
1.3 mum In1-xGaxAsyP1-y/InP lasers with compressive and tensile strained quantum wells have been found to lase in both transverse electric (TE) and transverse magnetic (TM) polarizations. Amplified spontaneous emission spectra indicate gain in both TE and TM modes. The relative magnitudes depend on device length and injection current. This structure can be used as a polarization insensitive optical amplifier.
