摘要

By combing artificial micro-nano structures,photonic crystals (PCs),with traditional semiconductor laser material to realize the dynamic collaborative control of photonic states and confined electrons,the band engineering of the PC has been confirmed.This brings new development space for the semiconductor laser,such as for low threshold and high efficiency.Based on a series of works by Zheng's group,this paper has reviewed kinds of PC lasers including electrical injection PC vertical cavity and lateral cavity surface-emitting lasers,and PC high beam quality lasers,to show that the PC is vital for promoting the continuous improvement of semiconductor laser performance at present and in the future.
