Beschreibung
Zusammenfassung:	A Mach-Zehnder interferometer for performing an optical function on a plurality of optical fibers is provided. The interferometer includes a first cane segment surrounding the optical fibers. The first cane segment forms a first optical coupling region. The interferometer also includes a second cane segment surrounding the optical fibers. The second cane segment forms a second optical coupling region. A phase shift region is formed by a discontinuity between the first and second cane segments for exposing the optical fibers. The optical fibers are suspended between the first and second cane segments within the phase shift region. A substrate is provided for supporting the optical fibers within the phase shift region.
