Abstract

Abstract An adjustable fiber optic polarizer (10) comprising tubular member (14) and a bulk polarizer (12) disposed within tubular member (14) and including a two-axes adjusting device (20) disposed in each end of the tubular member (14). Interface device (40) can be positioned in the two-axes adjusting device (20). The two-axes adjusting device (20) supports an interface device (40) which connects the fiber optic to the graded index lens (42). Adjusting device (20) permits two-axes motion of the supported lens (42) with respect to the bulk polarizer (12). The two-axes positioning device (20) can also be rotated with respect to the bulk polarizing device (12) for a maximum optical throughput and polarization extinction ratio.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 91 words
A fiber optic polarizer comprising: a tubular member; a bulk polarizer disposed within said tubular member; a first fiber optic to graded index lens interface device disposed in one end of said tubular number; a second fiber optic to graded index lens interface device disposed in the other end of said tubular member; first adjusting means for two-axes adjusting of the first graded index lens with respect to the bulk polarizer; and second adjusting means for two axes adjusting of the second graded index lens with respect to the bulk polarizer.
Claim 2
Dependent Claim 91 words
A fiber optic polarizer comprising: a tubular member; a bulk polarizer disposed within said tubular member; a first fiber optic to graded index lens interface device disposed in one end of said tubular number; a second fiber optic to graded index lens interface device disposed in the other end of said tubular member; first adjusting means for two-axes adjusting of the first graded index lens with respect to the bulk polarizer; and second adjusting means for two axes adjusting of the second graded index lens with respect to the bulk polarizer.
Claim 3
Dependent Claim 80 words
A fiber optic polarizer as claimed in claim 1 wherein said first and second adjusting means each comprise: a base member adjustably secured to one end of said tubular members second; a central member supported from said base member and disposed within said tubular member; a front member supported from said central member; and, adjusting screw means accessible from an exposed portion of said base member for two axes adjusting of said front member with respect to said base member.
Claim 4
Dependent Claim 49 words
A fiber optic polarizer as claimed in claim 2 wherein said adjusting screw adjusting means comprise; a first set screw disposed in said base member which contacts and positions said central member; and, a second set screw disposed in said base member which contacts and positions said front member.
Claim 5
Dependent Claim 31 words
A fiber optic polarizer as claimed in claim 3 wherein: said front member has an opening formed therein for securing said first or second fiber optic to graded index lens interface.
Claim 6
Dependent Claim 78 words
A fiber optic polarizer as claimed in claim 4 wherein said first and second fiber optic to graded index lens interface devices each comprise: an elongated cylindrical member having an elongated channel formed therein; a hole formed in one end of said elongated cylindrical member for receiving a graded index lens; and, three gauge pins disposed in the elongated channel and securing there between a single mode optic fiber in alignment and contact with the graded index lens.
Claim 7
Dependent Claim 77 words
A fiber optic polarizer as claimed in claim 1 wherein said first and second fiber optic to graded index lens interface devices each comprise: an elongated cylindrical member having an elongated channel formed therein; a hole formed in one end of said elongated cylindrical member for receiving a graded index lens; and, three gauge pins disposed in the channel and securing there between a single mode optic fiber in alignment and contact with the graded index lens.
Claim 8
Dependent Claim 125 words
A fiber optic bulk polarizer system comprising: a bulk polarizer supported within a housing; a first graded index lens having a single mode optical fiber secured to one end and having the other end disposed in proximity to said bulk polarizer; a second graded index lens having a single mode optical fiber secured to one end and having the other end disposed in proximity to said bulk polarizer; first adjusting means supporting said first graded index lens from said housing for two axes adjusting of said first graded index lens with respect to said bulk polarizer; and, second adjusting means supporting said second graded index lens from said housing for two axes adjusting of said second graded index lens with respect to said bulk polarizer.
Claim 9
Dependent Claim 125 words
A fiber optic bulk polarizer system comprising: a bulk polarizer supported within a housing; a first graded index lens having a single mode optical fiber secured to one end and having the other end disposed in proximity to said bulk polarizer; a second graded index lens having a single mode optical fiber secured to one end and having the other end disposed in proximity to said bulk polarizer; first adjusting means supporting said first graded index lens from said housing for two axes adjusting of said first graded index lens with respect to said bulk polarizer; and, second adjusting means supporting said second graded index lens from said housing for two axes adjusting of said second graded index lens with respect to said bulk polarizer.
Claim 10
Dependent Claim 81 words
A fiber optic bulk polarizer system as claimed in claim 7 wherein said first and second adjusting means each comprise: a base member adjustably secured to one end of said housing; a central members supported from said base member and disposed within said housing; a front member supported from said central member; and, screw adjusting means disposed within said base member and accessible from outside of said housing for two axes adjusting of said front member with respect to said housing.
