摘要： An all-fiber mode-field resizer comprises a first optical fiber configured to propagate signal light in a predetermined transverse mode along a longitudinal axis from a first input/output (I/O) port to a second I/O port. The first fiber is configured to have a first effective mode-field area and a first core V-parameter proximate the first I/O port and to have a second effective mode-field area and a second core V-parameter proximate the second I/O port. The second mode-field area is greater than the first mode-field area, and the second V-parameter is less than the first V-parameter. In one embodiment, the second V-parameter is less than approximately 1.3, and preferably less than 1.0. In another embodiment, the first V-parameter is greater than approximately 1.8. In yet another embodiment, our mode-field resizer is incorporated into a tapered fiber bundle.

摘要： A large mode area optical fiber is configured to support multiple transverse modes of signal radiation within its core region. The fiber is a hybrid design that includes at least two axial segments having different characteristics. In a first axial segment the transverse refractive index profile inside the core is not radially uniform being characterized by a radial dip in refractive index. The first segment supports more than one transverse mode. In a second axial segment the transverse refractive index profile inside the core is more uniform than that of the first segment. The two segments are adiabatically coupled to one another. Illustratively, the second segment is a terminal portion of the fiber which facilitates coupling to other components. In one embodiment, in the first segment M12>1.0, and in the second segment M22 >1.0 and M22˜1.0. In another embodiment, the optical fiber is coupled to a fiber stub.
