Patent ID: 7597486

Claim:
An optical device comprising: a body at least a portion of which is formed from a material that is transmissible to light, the body configured to be positioned in an optical sub-assembly between an optoelectronic transducer and a port configured to receive an optical fiber, wherein the optoelectronic transducer and the optical fiber collectively define an axis extending between a point on an optically active portion of the optoelectronic transducer and a point on a surface of the optical fiber, the body being configured to be positioned along the axis; a first surface of the body configured to be offset by a first angle from a plane that is perpendicular to the axis; and a second surface of the body configured to be offset by a second angle from the plane, the second angle being different from the first angle, wherein the first surface and the second surface are positioned at respective opposing ends of the body.
