Abstract
Birefringence in an InGaAsP/InP tensile-strained bulk semiconductor optical amplifier (SOA) is demonstrated by a polarization resolved amplified spontaneous emission (ASE) spectrum. A mode sum/min approach is used to investigate the periodicities in the ripple for transverse electric (TE) and transverse magnetic (TM) polarizations. The signal-induced birefringence in the SOA, which leads to polarization rotation of a probe beam, is presented in the format of the Poincare sphere. All-optical wavelength conversion (inverted and non-inverted) based on cross polarization modulation (XPolM) is realized. The impact of cross gain modulation (XGM) in XPolM is initially studied.
