Abstract

The application of strain in quantum-wells leads to polarization dependence in their absorption characteristics. Material containing compressively strained quantum-well layers (such as used in the POLarization based Integration Scheme, POLIS) shows enhanced interaction with the TE polarization. Devices fabricated on such material are affected by the polarization dependence as well. For slanted side-wall polarization converters this leads to different effective conversion lengths for the TE and TM polarization. Simulations show that the polarization dependent absorption affecting these devices is saturable and therefore power dependent. The simulations have been confirmed by measurements on experimental devices.
