Grating for tuning a light source |
| 摘要 |
A system includes a light source and a grating cube. The grating cube includes a transmission volume holographic grating positioned between two prisms. The transmission volume holographic grating diffracts part of a light source emission toward a reflective surface, producing diffracted light. At least some of the diffracted light is reflected off of the reflective surface, producing feedback light. The feedback light is fed back to the light source, thereby causing the light source emission to have the same wavelength as the feedback light. |

1. A system, comprising:
a light source; and a grating cube that comprises a transmission volume holographic grating positioned between two prisms; wherein:
the transmission volume holographic grating diffracts a desired wavelength of light;at least some diffracted light produced by the transmission volume holographic grating is reflected off of a partially reflective surface, producing feedback light; andthe feedback light is fed back to the light source, thereby causing a light source emission to have the same wavelength as the feedback light. |
