Title:
単一モード光ファイバーカップリングシステム
Document Type and Number:
Japanese Patent JP4932993
Kind Code:
B2
Abstract:
Coupling devices for coupling a lens to a single mode optical fiber are disclosed. In one aspect, a lens alignment assembly is the coupling device and includes a single mode optical fiber, a lens, and a locating tube. The locating tube includes a hollow bore having an internal diameter such that the lens and single mode optical fiber are held in a tight, sliding fit within the locating tube. In another aspect, the device includes a single mode optical fiber located adjacent to a cylindrically shaped lens. The lens includes an angled facet having a reflective surface for directing light normal, or near normal, to the optical axis. The lens further includes a flat surface opposite the angle facet. The lens and single mode optical fiber are rotatable to scan a region of a biological surface. In another aspect, a rotatable optical fiber coupler includes a receptacle, a single mode optical fiber, and a GRIN rod lens having a portion thereof ground and polished such that the rod lens forms a tight, sliding fit within the receptacle. The rod lens, single mode optical fiber, and receptacle are all concentrically aligned with the optical axis. In still another aspect, the rotatable optical fiber coupler includes an aspheric lens.
