摘要：
Novel behavior of laser diodes (LDs) and superluminescent diodes (SLDs) fabricated on substrates with nonidentical quantum wells has been discovered. Mirror-imaged nonidentical quantum well (QW) lasers/superluminescent diodes have been designed, fabricated, and measured. Nonuniform carrier distribution inside multiple quantum wells is further verified experimentally. Measured characteristics also show that electrons, instead of holes, are the dominant carrier affecting carrier distribution. The sequence of the nonidentical QW is also shown to have significant influence on device characteristics, showing very different carrier distribution in each sequence.
