Beschreibung
Zusammenfassung:	The invention relates to a nonlinear interferometer (400) comprising: - a first glass plate (480A) optically coupled to a second glass plate (480B), forming a space (410) therebetween; - a first phase bias element (430) residing inside the space (410) and protruding partially into the space (410) wherein the phase bias element (430) introduces a phase shift in at least one channel of an optical signal; - a first reflective coating (420) residing inside the space (410) and on the second glass plate (480B); and - a second reflective coating (440) residing inside the space (410) and on the first glass plate (480A), wherein the first and second reflective coatings (420,440) broaden a pass band of the optical signal.
