Interposer with alignment features
First Claim
1. An optical interposer for optically coupling light between an OED supported on a substrate and an optical fiber, the interposer comprising:
- an interposer of an optically-clear moldable material comprising at least the following features;
a port for receiving a ferrule containing at least one optical fiber, said port comprising an interface surface positioned to optically couple with an end face of said optical fiber;
an active lens adapted to optically couple with an OED, said active lens and said interface surface optically coupled along an optical path in said interposer;
a protrusion extending backward from said port, said protrusion defining a first register surface, said first register surface being a certain distance from said optical path such that, when a second register surface of a ferrule containing said optical fiber contacts said first register surface, a front portion of said ferrule is aligned to be received in said port.

Abstract
An optical interposer for optically coupling light between an OED supported on a substrate and an optical fiber, the interposer comprising: (a) an interposer of an optically-clear moldable material comprising at least the following features: (b) a port for receiving a ferrule containing at least one optical fiber, the port comprising an interface surface positioned to optically couple with an end face of the optical fiber; (c) an active lens adapted to optically couple with an OED, the active lens and the interface surface optically coupled along an optical path in the interposer; (d) a protrusion extending backward from the port, the protrusion defining a first register surface, the first register surface being a certain distance from the optical path such that, when a second register surface of a ferrule containing the optical fiber contacts the first register surface, the ferrule is aligned with the port such that the port can receive a front portion of the ferrule if the ferrule is pushed forward.

20. An interposer for optically coupling light between an OED supported on a substrate and an optical fiber, the interposer comprising:
a lens body of an optically-clear moldable material comprising at least the following features; a port for receiving a ferrule containing at least one optical fiber, said port comprising an interface surface positioned to optically couple with an end face of said optical fiber; an active lens adapted to optically couple with an OED, said active lens and said interface surface optically coupled along an optical path in said interposer; a reflective surface disposed along said optical path to bend light between said active lens and said interface surface, said reflective surface being an air interface formed by a cavity in the top of said body, said cavity is defined by said reflective surface, a forward wall at about 55 to about 110°
relative to said reflective surface, a rear wall at about 135 to about 180°
relative to said reflective surface, and side walls at about 90 to about 120°
relative to said reflective surface.- View Dependent Claims (21, 22)
