Abstract
We demonstrate a wide tuning range high-speed wavelength-swept semiconductor laser based on a polygon scanning filter that is common to two laser cavities. Linear wavelength tuning was achieved over 145 nm around 1310 nm at a tuning repetition rate of 20 kHz. The wavelength tuning filter is expandable to accommodate multiple semiconductor optical amplifiers for further widening of the laser wavelength tuning range.
摘要
我们展示了一种基于多边形扫描滤波器的宽调谐范围高速波长扫描半导体激光器，该滤波器为两个激光腔所共用。在1310nm附近实现了145nm的线性波长调谐，调谐重复率为20kHz。波长调谐滤波器可扩展，以容纳多个半导体光放大器，从而进一步拓宽激光器的波长调谐范围。
