英文摘要
The main purpose of this research is to clarify the static and dynamic properties of a novel distributed reflector (DR) dynamic single mode laser.Specific results obtained in this research are as follows.The DR laser was theoretically investigated focusing on its high efficiency and high power operation as well as its single mode operation.1.5 mu m GaInAsP/InP DR laser was realized by using the big structure and OMVPE buried deep corrugation. High front of rear output power ratio, as well as low threshold current operation and large side-mode suppression ratio (SMSR) were obtained by introducing asymmetric grating using shallow grating in active region and deep grating in passive region.1.5 mu m GaInAsP/InP DR laser with SCH structure was realized using the BIG structure and OMVPE buried asymmetric corrugation. The narrow line width and small chirping characteristics of DR laser were verified experimentally.DR laser was theoretically investigated focusing on its narrow line width operation as well as high efficiency and high power operation.
