Abstract: The invention relates to an optical assembly (100) comprising a first optical fiber (101) propagating coherent light in a predetermined direction (P) into an input end (110) of the optical assembly (100), said optical fiber having a core and a cladding; a heat sink (111) surrounding the optical fiber (101) at the input end (110); and a lens (120) arranged after the heat sink (111) in the propagating direction (P). The optical assembly (100) further comprises a filter (130) arranged after the lens (120), wherein the filter (130) has a reflective surface (131) arranged to transmit light having one or more desired wavelengths and to reflect one or more undesired wavelengths back through the lens (120). The invention further relates to a method for separating desired and undesired wavelengths.

Abstract: An optoelectronic component for receiving light. A housing including an axially extending cavity is arranged to receive an incoming beam. At least one adjustable arrangement includes at least one lens and a first adjustment module configured to adjust a focal point of the lens relative to an end surface of an optical fiber connectable to the housing. A first body is arranged to influence a position of the lens. A second body contacting the first body is journalled in the housing. The first adjustment module is arranged to act on the first body to rotate the first body spherically around a distant point and to alter the position of the lens, in order to locate a focal point of the lens on an end surface of the optical fiber.

Abstract: A terminated hollow-core optical fiber includes a capillary, a hollow-core optical fiber including a structured cladding, and an endcap. A first end of the hollow-core optical fiber terminates inside the capillary a non-zero distance away from a first end face of the capillary. The hollow-core optical fiber is adhered to the capillary at a second end face of the capillary where the hollow-core optical fiber extends out of the capillary. The endcap is fused to the first end face of the capillary. The endcap has a larger diameter than the first end of the hollow-core optical fiber. This termination scheme does not require fusing the hollow-core fiber itself to the endcap or any other part. Therefore, this termination scheme is applicable to hollow-core fibers with a structured cladding that cannot tolerate the temperatures associated with fusing the hollow-core fiber to another part.

Abstract: An optoelectronic assembly connectorizing light through an optical fiber. A housing includes an axially extending cavity. A transparent window is located at a first end of the cavity. A termination part is located at a second end of the cavity. The cavity forms a cooling chamber being fed by a flowing coolant surrounding an envelope surface of the optical fiber. The optical fiber is in optical contact with the window and extends out of the assembly through the termination part. The optical fiber is fixed in the termination part with a guiding glue.

CPC classification number: G02B6/4286 , G02B6/4269
Abstract: A fiber-optic cable includes an optical fiber that transports a forward-propagating laser beam. The optical fiber includes a core, a cladding, and an output end-face emitting the forward-propagating beam. The fiber-optic cable also includes a mode-stripper, along a segment of the optical fiber, that couples out backward-propagating radiation that has been coupled into the cladding at the output end-face. The fiber-optic cable further includes a waveguide having a waveguide body with a bore containing at least part of the segment of the optical fiber. The bore is defined by an inward-facing surface that guides at least a fraction of the backward-propagating radiation, coupled out of the cladding by the mode-stripper, toward a rear opening of the bore farthest from the output end-face. Additionally, the fiber-optic cable includes one or more sensors or fiber ports that receive portions of the backward-propagating radiation emerging from the rear opening.
