Claims8
An apparatus for exchanging a communicated optical signal between an optical information bus and an electro-optical component, such apparatus comprising:
- A) a flat surface, for diverting at a substantially predetermined angle at least a portion of an optical signal between an axis of transmission within a waveguide of the optical information bus and an axis of transmission of the optical component, disposed on the wave-guide at substantially a forty-five degree angle to the axis of transmission within the wave-guide and the axis of transmission of the component, with a polymer resin at least partially disposed between the flat surface and an object of transmission on the electro-optical component;
- B) means for focusing the optical signal with respect to the electro-optical component and the waveguide;
- and
- C) means for maintaining a predetermined spatial relationship of the means for focusing and the electro-optical component.
An apparatus for exchanging a communicated optical signal between an optical information bus and an electro-optical component, such apparatus comprising:
- A) means for diverting, at a substantially predetermined angle, at least a portion of an optical signal between an axis of transmission within a waveguide of the optical information bus and an axis of transmission of the optical component;
- B) a spherical ball lens with a sphericity that is substantially one-half wave-length of the optical signal for focusing the optical signal with respect to the electro-optical component and the waveguide;
- and
- C) means for maintaining a predetermined spatial relationship of the means for focusing and the electro-optical component.
A method for exchanging a communicated optical signal between a substantially continuous optical information bus and an electro-optical component, such method comprising the steps of:
- A) disposing a flat surface on a wave-guide of the optical information bus at substantially a forty-five degree angle to the axis of transmission within the wave-guide and the axis of transmission of the component;
- B) diverting at substantially a right angle at least a portion of an optical signal between an axis of transmission within the waveguide to an axis of transmission of the component;
- B) focusing the optical signal between the component and the waveguide;
- and
- C) transceiving the optical signal within the electro-optical component.
