Abstract
En 中文
The research and development of wavelength-tunable lasers has always attracted much attention due to their huge potential applications in the fields of biomedicine, spectroscopy, information science, and integrated optics. Semiconductor materials with asymmetric center structures, such as ZnO, GaN, CdS, and perovskite, exhibit both piezoelectric and piezoresistive effects, which provide a feasible path for the realization of lasing mode selective output and dynamic modulation. In this review, the dynamic regulation of lasing mode output is obtained in different semiconductor optical cavity in succeed, and realized the single-mode laser by utilizing the synergistic effect of piezoelectricity and piezoresistivity. In addition, the application of this modulated method in the field of nonlinear optics and strain sensing is also further explored and expanded. This series of research results fully proves that this modulation mechanism is not only suitable for the dynamic regulation of the resonant frequency of cavity mode in different material systems, but also provides an effective strategy for the development of a new type of non-contact, high-precision strain sensors by taking advantage of the ultra-narrow pulse width lasing mode-shift.
