Abstract

An optical subassembly comprising: (a) an interposer having first and second opposing sides and defining an alignment aperture extending from said first opposing side to said second opposing side, said interposer defining traces having contacts; (b) a fiber having a first optical axis, said fiber being held such that first optical axis is positioned essentially orthogonal to said first and second opposing sides; (c) at least one optical component mounted to said second opposing side and being electrically connected to at least a portion of said contacts, said at least one optical component having a second optical axis coincident with said first optical axis; and (d) a circuit board configured to receive said interposer such that said interposer is essentially orthogonal to said circuit board and said first optical axis is essentially parallel to said circuit board, said circuit board being electrically connected to at least a portion of said contacts.

Dependent claims

An optical subassembly comprising:

an interposer, said interposer being rigid and planar, and having first and second opposing sides and defining at least one alignment aperture extending from said first opposing side to said second opposing side, said interposer defining traces having first, second, and third contacts, said first contacts being configured for electrical connection to at least one optical component, said second contacts being configured for electrical connection to at least one chip, and said third contacts being configured for electrical connection to a circuit board;
at least one fiber having a first optical axis, said fiber being held such that said first optical axis is positioned essentially orthogonal to said first and second opposing sides;
said at least one optical component mounted to said second opposing side and being electrically connected to at least a portion of said first contacts, said at least one optical component having a second optical axis coincident with said first optical axis;
said at least one chip for operating said at least one optical component, said at least one chip being mounted on said first or second opposing side and electrically connected to at least a portion of said second contacts;
and
said circuit board configured to receive said interposer such that said interposer is essentially orthogonal to said circuit board, said circuit board being electrically connected to at least a portion of said third contacts.
