P. Steinmann et al., ASYMMETRIC QUANTUM-WELLS WITH ENHANCED QCSE - MODULATION BEHAVIOR ANDAPPLICATION FOR INTEGRATED LASER MODULATOR/, IEEE photonics technology letters, 9(2), 1997, pp. 191-193
We have optimized asymmetric QW's with respect to the QCSE, We have fo
und structures with a red shift of 40 meV at a field of 70 kV/cm. More
over, it was our aim to find structures with a strong blue shift, A ne
w principle for the integration of a laser and a modulator is presente
d, which is based on the application of blue shift asymmetric QW's in
the active layer for laser and modulator simultaneously. A calculation
of the laser and modulation properties for a QW-structure with 27 meV
blue shift at a field variation of 70 kV/cm is presented.
