摘要:
The present invention relates in general to semiconductor light emitting devices and in particular to methods of altering the spatial emission patterns of such devices. A known problem with these prior art light emitting devices (and laser diodes in general) is that their far-field emission patterns are elliptical and astigmatic in nature. The present invention addresses this problem by refractive index perturbations in the semiconductor device aligned in a direction substantially transverse to the light emission direction to achieve a desired spatial distribution of the emission.
摘要(中):
本发明一般涉及半导体发光器件,尤其涉及改变这种器件的空间发射图案的方法。 这些现有技术的发光装置(通常为激光二极管)的已知问题在于它们的远场发射图案本质上是椭圆形和散光的。 本发明通过在基本上横向于发光方向的方向上对齐的半导体器件中的折射率扰动来解决这个问题,以实现发射的期望的空间分布。
