摘要
提出了一种新型单片集成大范围可调谐半导体激光器——多通道干涉(MCI)激光器,采用多臂干涉进行选模,制作简单且容差大。基于电光效应调谐的MCI激光器波长调谐范围大于40 nm,在整个调谐范围内的边模抑制比(SMSR)大于40 dB,且激光器与半导体光放大器集成的器件出纤功率大于13 dBm。基于热光效应调谐的MCI激光器波长调谐范围大于45 nm,在整个调谐范围内的SMSR大于48 dB,线宽小于250 kHz,总的热调谐功耗低于50 mW。具体阐述了器件的理论设计、器件制作以及器件的测试。
Abstract
We propose a new monolithic widely tunable semiconductor laser?multi-channel interference (MCI) laser. Multi-arm interference is used for mode selection, which is simple to manufacture and has large tolerance. The wavelength tuning range of the MCI laser based on the electro-optic effect is more than 40 nm, the side mode suppression ratio (SMSR) is more than 40 dB in the whole tuning range, and the fiber output power of the device integrated with the laser and the semiconductor optical amplifier is more than 13 dBm. In the meanwhile, the wavelength tuning range of the MCI laser based on thermo-optical effect is greater than 45 nm, the SMSR is larger than 48 dB, the line width is less than 250 kHz, and the total thermal tuning power consumption is less than 50 mW. In this paper, the theoretical design, fabrication, and test of the device are described in detail.
