| 英文摘要 | An apparatus for collimating radiation can include an aperture of subwavelength dimensions and a neighboring set of grooves defined on a metal film integrated with an active or passive device that emits radiation. Integration of the beam collimator onto the facet of a laser or other radiation-emitting device provides for beam collimation and polarization selection. Beam divergence can be reduced by more than one order of magnitude compared with the output of a conventional laser. An active beam collimator with an aperture-groove structure can be integrated with a wide range of optical devices, such as semiconductor lasers (e.g., quantum cascade lasers), light emitting diodes, optical fibers, and fiber lasers. |
