Integrated high speed modulator for grating-outcoupled surface emitting lasers

Image Number 4 for United States Patent #7313158.

A single-mode grating-outcoupled surface emitting (GSE) semiconductor laser architecture is provided. This architecture enables high speed modulation of the GSE laser, which is accomplished by only varying the relative phase of counter propagating waves in the outcoupler grating region of the lasing cavity.
