Abstract

Optimization of design structure of single-mode electrically-pumped ZnO nanowire laser (NWL) with including of distributed Bragg reflector (DBR), acting as a rear mirror, has been achieved. Numerical simulation results show that the design structure of ZnO NWL with DBR has better performance compared to the same design structure but without DBR. Lower threshold current, higher output power, and higher quality factor (Q-factor) is observed of ZnO NWL with DBR..
