Modeling of DFB surface emitting lasers and semiconductor laser arrays

Theoretical modeling of novel semiconductor laser systems, i.e., distributed-feedback (DFB) surface emitting lasers and semiconductor laser arrays, is presented. The DFB surface emitting lasers can produce stable single-mode outputs even under high bit-rate direct modulation and form two-dimensional laser arrays. A simple and accurate analytical model using the coupled-mode theory is developed to describe these surface emitting lasers. Due to the simplicity of the model, the desired laser output characteristics, i.e., low threshold condition, large side mode suppression ratio, and stable and low noise Bragg-mode outputs, can be obtained by systematically optimizing the device length, optical coupling and phase shifter in the device.
