Abstract
A hermetically sealed, opto-electronic array housing assembly having a ceramic base, electrical connectors, a metal can, and a glass window. The glass window can support a micro-lens array. The metal can receives the glass window. The electrical impedance of the electrical connectors is beneficially carefully controlled to enable high-speed data communications. A multi-element optical fiber connector can provide for optical communications to and/or from an opto-electronic array contained within the housing.
Claims22
An opto-electronic housing, comprising:
- a substantially planar submount having a plurality of conductive traces on a planar surface thereof;
- a metallic can attached to the planar surface of said submount forming a cavity having the planar surface of said submount on a first surface thereof and said can on at least a second surface thereof, said cavity having an opening for light to pass through;
- and
- a transparent window in or covering said opening and attached to said can;
- wherein said plurality of conductive traces extend along the planar surface of the submount from inside the cavity to beyond the can;
- and
- wherein said cavity is hermetically sealed and comprises said window on a first surface, said submount on an opposing second surface, and said can on the surfaces interconnecting said window and said submount.
An opto-electronic device, comprising:
- a substantially planar submount comprising substantially planar surface;
- a plurality of thru-via conductive contacts passing through said planar surface;
- a plurality of opto-electronic devices mounted directly or indirectly on said submount, wherein each of said plurality of opto-electronic devices is in communication with at least one of said conductive contacts;
- a metallic can attached to the planar surface of said submount and forming a cavity, wherein said can includes an opening for light to pass through, and wherein said cavity extends over said opto-electronic devices and said conductive contacts;
- and
- a transparent window in or covering said opening and attached to said can;
- wherein said cavity is hermetically sealed and comprises said window on a first surface, said submount on an opposing surface, and said can on the surfaces interconnecting said window and said submount.
An opto-electronic housing, comprising:
- a substantially planar submount holding an opto-electronic array having a plurality of opto-electronic devices;
- a metallic support comprising a central body, parallel legs, and guide pins, wherein said support is attached to said substantially planar submount and forms a cavity with an opening for light to pass through;
- and
- a transparent window in or covering said opening and attached to said support, wherein a hermetic seal is formed, and wherein a cavity is formed, said cavity comprising said window on a first surface, said submount on an opposing surface, and said support on the surfaces interconnecting said window and said submount;
- wherein a flexible ribbon-type optical cable having a plurality of optical fibers and openings that align with the guide pins can be mounted between said parallel legs, said guide pins fitting into said openings when the flexible ribbon-type optical cable is attached to said support.
