利用外腔半导体激光器 (ECLD)在不同频率振荡所需的阈值载流子密度的表达式及相关的折射率表达式研究了它的双稳特性 ,由此导出了在外腔半导体激光器的P ν (功率 频率 )曲线上出现双稳的条件以及双稳环宽度的解析表达式。
The bistable characteristics of the external cavity semiconductor laser (ECLD) oscillating at different frequencies are studied by using the expression of the threshold carrier density and the related refractive index expressions. Power frequency) curves appear bistable conditions and bistable ring width analytic expression.
