A fieldhyphen;effect quantumhyphen;well laser with lateral current injection

摘要

Polarizationhyphen;dependent gain switching in a fieldhyphen;effect quantumhyphen;well laser with lateral current injection is studied. We use theksdot;pmethod for the optical dipole matrix and take into account the intraband relaxation. Gain switching is achieved by the field effect from a gate terminal in a lateral current injection quantumhyphen;well laser structure. It is shown that the peak gain exhibits a red shift and the peakhyphen;gain amplitude decreases with an increasing electric field for the TE mode. The TM mode is less affected by the external field.
