Abstract
A set of interlocking modules supports and connects a die containing lasers, a set of precision molded lenses and a set of beam switching elements. Another embodiment of the invention is a structure for mounting a logic chip and an optical chip on a chip carrier, with the optical chip being mounted on the side of the carrier facing the system board on which the carrier is mounted, so that radiation travels in a straight path from optical sources on the optical chip into optical transmission guides on the board.
Claims16
An assemblage structure of components for supporting at least one optical chip and at least one electronic chip and connecting said chips to a system support comprising:
- a chip carrier having electrical interconnection disposed thereon and having a lower side facing said system support and an upper side facing opposite said system support;
- at least one optical chip mounted on said lower side and having at least one radiation emitting component emitting radiation perpendicular to said optical chip and traveling toward said system support;
- at least one electronic chip that processes data mounted on said upper side;
- in which said optical chip is mounted aligned with at least one optical transmission medium disposed on said system support, whereby radiation emitted by said at least one radiation emitting component travels along a direct path between said optical chip and said transmission medium;
- wherein said system support lies within a plane parallel to the chip carrier and wherein said optical transmission medium is a solid waveguide wholly within said plane of the system support;
- and
- further comprising at least one optical transfer unit aligned between said at least one optical chip and comprising lenses that focus radiation emitted by said at least one optical chip on to said optical transmission medium, wherein a rim of the optical transfer unit fits to a vertical edge of a step of the optical chip to align the lenses with the optical chip.
An assembly structure of components for supporting at least one optical chip and at least one electronic chip and connecting said chips to a system support comprising:
- a system support wherein said system support lies within a plane;
- a chip carrier having electrical connections disposed thereon and having a lower side facing said system support and an upper side facing opposite said system support;
- at least one optical chip directly mounted only on said chip carrier and only on said lower side and having at least one radiation emitting component emitting radiation perpendicular to said optical chip and traveling toward said system support;
- at least one electronic chip that processes data mounted on said upper side;
- at least one solid waveguide within the plane of the system support, wherein said optical chip is aligned with the at least one solid waveguide, so that radiation emitted by said at least one radiation emitting component travels along a direct path between said optical chip and said at least one solid waveguide and wherein said system support lies within a plane parallel to the chip carrier and wherein said at least one solid waveguide is wholly within the plane of the system support;
- further comprising at least one optical transfer unit aligned between said at least one optical chip and comprising lenses that focus radiation emitted by said at least one optical chip on to said optical transmission medium, wherein a rim of the optical transfer unit fits to a vertical edge of a step of the optical chip to align the lenses with the optical chip.
An assembly structure of components for supporting at least one optical chip and at least one electronic chip and connecting said chips to a system support comprising:
- a system support wherein said system support lies within a plane;
- a chip carrier having power connections and signal connections disposed thereon and having a lower side facing said system support and an upper side facing opposite said system support;
- at least one optical chip mounted only on said chip carrier and only on said lower side and having a plurality of radiation emitting components emitting radiation perpendicular to said optical chip and traveling toward said system support;
- at least one electronic chip that processes data mounted on said upper side, said at least one electronic chip having power and signal connections in contact with the power and signal connections of said chip carrier;
- a plurality of solid waveguides within the plane of the system support, wherein said optical chip is aligned with the plurality of solid waveguides, so that radiation emitted by said plurality of radiation emitting components travels along a direct path between said optical chip and said plurality of solid waveguides;
- and
- further comprising at least one optical transfer unit aligned between said at least one optical chip and comprising lenses that focus radiation emitted by said at least one optical chip on to said optical transmission medium, wherein a rim of the optical transfer unit fits to a vertical edge of a step of the optical chip to align the lenses with the optical chip.
