Integrated sub-wavelength grating system |
摘要 |
An integrated grating element system includes a first transparent layer formed on an optoelectronic substrate layer which includes at least two optoelectronic components, a first grating layer disposed on the first transparent layer which includes at least two sub-wavelength grating elements formed therein aligned with active regions of the optoelectronic components, and a second grating layer placed at a distance from the first grating layer such that light propagates between a diffraction grating element formed within the second grating layer and the at least two sub-wavelength grating elements. |

1. An integrated grating element system comprising:
a first transparent layer formed on an optoelectronic substrate layer, said optoelectronic substrate layer comprising at least two optoelectronic components; a first grating layer disposed on said first transparent layer and having a higher refractive index than the first transparent layer, said grating layer comprising at least two sub-wavelength grating elements formed therein aligned with active regions of said optoelectronic components, wherein the at least two sub-wavelength grating elements each focus, collimate, or bend a beam of light, and wherein the at least two sub-wavelength grating elements form a high contrast subwavelength grating having a pattern that varies in at least two dimensions; and a second grating layer at a distance from said first grating layer such that light propagates between a diffraction grating element formed within said second grating layer and said at least two sub-wavelength grating elements, wherein the at least two optoelectronic components comprise optical sources and the system functions as a multiplexer, or the at least two optoelectronic components comprise optical detectors and the system functions as a demultiplexer. |
