due to many important applications, the group iii-nitride semiconductors have recently attractedremarkable attention among semiconductor researchers and engineers. in this paper, we report on the impact of extrinsic and temporal carriers on the screening of polarization internal fields. the optical efficiency of gan/algan multiple quantum well (mqw) nanostructures were studied by means of photo...

Electroabsorption modulators (EAMs) based on the quantum confined Stark effect have advantages in applications that require high speed, low drive voltage, and high extinction ratio. They are promising devices for external signal modulation in high-bandwidth optical communication systems. EAMs can be integrated with other devices like laser diodes, semiconductor optical amplifiers, and mode tran...
