Using a two-step process, distributed feedback (DFB) lasers at λ = 1.52 μm have been fabricated for the first time by gas source molecular beam epitaxy (GSMBE). The DFB heterostructure consists in InP confinement and quaternary contact layers regrown on a second order grating engraved in ...
DFB(Distributed Feedback)激光器是一种特殊的半导体激光器,它通过在激光器的有源区附近引入周期性的折射率变化来实现单模输出。这种周期性结构作为光栅,提供了反馈机制,使得激光器能够在特定的波长上工作,通常用于需要高精度波长控制和窄线宽的应用中,如光纤通信、光谱学等。 图1展示了半导体分布式反馈(DFB)激光器结构...
3 分布式反馈(DFB)激光波长的热调谐 调整DFB(分布式反馈)激光器的发射波长是通过改变影响其内部光学特性的参数来实现的。具体来说,可以通过温度调谐、电流调谐以及结合其他技术手段来进行。DFB激光器的工作原理依赖于内置布拉格光栅提供的周期性折射率变化,这使得只有满足特定条件的波长能够得到有效的反馈并形成稳定的激光...
