Abstract
A method of making an all-fiber Mach-Zehnder interferometer comprising at least two optical fibers comprises the steps of bringing the fibers in a reciprocal contact relationship for a contact section thereof; fusing together and tapering the fibers in at least a first portion of said contact section; forming at least two optical couplers between the fibers in a second and a third portions of said contact section, located at opposite sides of said first portion.

Method of making an all-fiber Mach-Zehnder interferometer comprising at least two optical fibers, characterized by comprising the following steps:
- bringing the fibers in a reciprocal contact relationship for a contact section thereof;
- fusing together and tapering the fibers in at least a first portion of said contact section;
- forming at least two optical couplers between the fibers in a second and a third portions of said contact section, located at opposite sides of said first portion.
All-fiber Mach-Zehnder interferometer comprising at least two optical fibers (201,202) in reciprocal contact relationship in a contact section (21,251,27,261,23,22,252,28,262,24) thereof and at least two optical couplers (5,6) respectively formed in a first (251,252) and second (261,262) portions of said contact section, characterized in that the fibers are fused together and tapered in at least a third portion (291,292), intermediate the first and second portions of the contact section.
