Abstract

Apparatus for mounting and interconnecting optical devices. The apparatus comprises generally rectangular members constructed of optical transparent material formed with recesses having sides positioned at angles with respect to a line perpendicular to a surface of the apparatus. Reflective material is selectively coated on ones of the recess sides such that a parallel coherent light beam emitted by one optical device mounted on the surface of the apparatus is reflected by the light reflective material of one recess side internally through the apparatus to the light reflective material of another recess side whereat it is reflected to optical devices mounted on the apparatus surface.

Claims

1. Apparatus for mounting and interconnecting optical devices comprising:

means formed of an optical transparent material and having recesses located therein with sides thereof each formed at an acute angle with respect to a line perpendicular to a mounting surface of said means and wherein selected ones of said recess sides are coated with a light reflecting material for receiving multiple parallel coherent light beams emitted by optical devices mounted on said mounting surface and deflecting said multiple light beams through said optical transparent material to others of said coated recess sides for receiving ones of said deflected light beams and deflecting said received one light beams through said optical transparent material to other said mounted optical devices.

2. The optical device mounting and interconnecting apparatus set forth in claim 1 wherein said recesses comprise:

a plurality of channels formed in surfaces of said optical transparent material with each channel having a side formed at said acute angle with respect to said perpendicular line and with ones of said channel sides selectively coated with said light reflecting material for receiving said emitted light beams and deflecting said light beams through said optical transparent material to optically interconnect mounted optical devices.

3. The optical device mounting and interconnecting apparatus set forth in claim 2 wherein said mounting and interconnecting apparatus comprises:

a pair of generally rectangular configured members each formed of said optical transparent material with parallel ones of said channels formed in opposing surfaces of each of said members and wherein said members are assembled one on top of the other with channels of one member rotated at a right angle with respect to channels of the other member and with selected ones of said channel sides coated with said light reflecting material for receiving said multiple light beams emitted by optical devices mounted on mounting surfaces of ones said members and deflecting said multiple light beams through said optical transparent material to interconnect multiple ones of said mounted optical devices.

4. The optical device mounting and interconnecting apparatus set forth in claim 3 wherein said mounting and interconnecting apparatus recesses comprise:

a plurality of terminal pads deposited on ones of said optical device mounting surfaces with each terminal pad corresponding with a terminal of one of said optical devices and selectively connected by conductor paths deposited on said mounting surfaces for electrically interconnecting said ones of said mounted optical devices to both externally power and control operation thereof.

5. The optical device mounting and interconnecting apparatus set forth in claim 1 wherein said mounting and interconnecting apparatus recesses comprise:

a plurality of apertures formed in surfaces of said mounting and interconnecting apparatus with each aperture having a generally polyhedral configuration wherein sides thereof are formed at acute angles with respect to said line perpendicular to said mounting surface and are selectively coated with said light reflecting material for receiving said emitted light beams and deflecting said light beams through said optical transparent material to optically interconnect ones of said mounted optical devices.

6. Apparatus for mounting and interconnecting optical devices comprising:

a generally rectangular configured member formed of an optical transparent material and having a plurality of parallel channels located therein with sides thereof each formed at an acute angle with respect to a line perpendicular to a mounting surface of said member and wherein specific areas of said channel sides are coated with a light reflecting material for receiving multiple parallel coherent light beams emitted by ones of the optical devices mounted on said mounting surface and deflecting said multiple light beams through said optical transparent material to other areas of said channel sides coated with said light reflecting material for receiving said deflected light beams and deflecting said received light beams through said optical transparent material to other ones of the optical devices mounted on said mounting surface.

7. Apparatus for mounting and interconnecting optical devices comprising:

a generally rectangular configured member formed of an optical transparent material having a plurality of apertures located therein for optically interconnecting optical devices mounted on a mounting surface of said member and wherein each aperture has a generally polyhedral configuration with sides thereof formed at acute angles with respect to a line perpendicular to said mounting surface and which sides are selectively coated with a light reflecting material to deflect multiple parallel coherent light beams emitted from ones of said mounted optical devices through said optical transparent material to other ones of said apertures wherein coated aperture sides of said other apertures deflect said emitted light beams to other ones of said mounted optical devices.

8. Apparatus for mounting and interconnecting optical devices comprising:

a pair of generally rectangular configured members each formed of optical transparent material with parallel channels formed in opposing surfaces of each of said members and wherein said members are assembled one on top of the other with channels of one member rotated at a right angle with respect to channels of the other member and with sides of said channels formed at acute angles with respect to a line perpendicular to an optical device mounting surface and selectively coated with a light reflecting material and which members have a plurality of terminal pads deposited on said mounting surface of said assembled members for use in mounting said optical devices on said mounting surface with each terminal pad corresponding with a terminal of one of said optical devices and with said terminal pads selectively interconnected by conductor paths deposited on said mounting surface for electrically interconnecting said mounted optical devices to both externally power and control operation thereof and wherein ones of said coated channel sides are positioned for receiving multiple parallel coherent light beams emitted by optical devices mounted on said mounting surface of said members and deflecting said multiple parallel coherent light beams through said optical transparent material to other ones of said coated channel sides for deflection to ones of said mounted optical devices.
