摘　　要：为增加可调谐激光器的波长调谐范围,提高系统的可靠性和稳定性,基于液晶的电控双折射特性,设计了一种中心波长为852 nm的内腔液晶可调谐垂直腔面发射激光器结构。分析了该结构获得宽范围波长调谐和单偏振稳定输出的物理原理,利用传输矩阵法进一步计算整个器件下不同液晶层厚度所对应的反射谱,得出不同液晶厚度和折射率下激光器的激射波长。结果表明,液晶可调谐激光器单偏振波长调谐范围达到31 nm,调谐效率大于10 nm/V。In order to increase the wavelength tuning range of the tunable laser and improve the reliability and stability of the system,a wavelength tunable vertical cavity surface emitting laser with a central wavelength of 852 nm was designed based on the characteristics of electrically controlled birefringence of liquid crystal.The physical principle that the structure obtained a wide range of wavelength tuning and single polarization stable output was analyzed,and the reflection spectra corresponding to the thickness of different liquid crystal layers under the whole device were further calculated by the transfer matrix method,the lasing wavelength of laser with different thickness and refractive index of liquid crystal was obtained.The results show that the tuning range of the liquid crystal tunable laser with single polarization reaches 31 nm and the tuning efficiency is more than 10 nm/V.
