Paper Abstract

The polarization dependence of 1550-nm SOAs based on tensile strained bulk InGaAsP is analyzed numerically, focusing on their wavelength and gain dependence. We demonstrate that strained bulk SOAs are applicable for a wide range of carrier density and wavelength. The gain spectra are calculated based on the k.p method, and the carrier-density and wavelength dependence of the gain is evaluated. We demonstrate that the optimization enables us to make SOAs whose gain polarization sensitivity is within 1 dB under a 20-dB gain in a 60-nm bandwidth in real devices.
