In one embodiment, an optical subassembly includes a housing, a ball lens, a constraining insert, and a ball lens constraint. The housing includes a fiber receptacle formed in a first end of the housing and a second receptacle formed in a second end of the housing opposite the first end. The fiber receptacle and second receptacle define a cavity through the housing from the first end to the second end of the housing. The ball lens and the constraining insert are disposed within the cavity. The ball lens constraint is configured to cooperate with the constraining insert to constrain the ball lens in three dimensions within the cavity.

Constraining ball lens in an optical subassembly

In one example, an optical device includes a body having a first surface and a second surface. At least a portion of the body is formed from a material that is transmissible to light. The body is configured to be positioned in an optical sub-assembly along an axis defined between an optoelectronic transducer and a port configured to receive an optical fiber. The axis is defined between a point on an optically active portion of the optoelectronic transducer and a point on a surface of the optical fiber. The first surface of the body is positioned at a first angle relative to a plane that is perpendicular to the axis. The second surface of the body is positioned at a second angle relative to the plane. The first surface and the second surface are positioned at respective opposing ends of the body.

Managing backreflection

In at least one example, an optical component includes a central optical surface proximate an optical axis, a peripheral portion extending radially from the central optical surface, and a stepped portion between the central optical surface and the peripheral portion. The stepped portion may be formed to raise the central optical surface above the peripheral portion.
