Abstract
A single fiber Mach-Zehnder interferometer comprises an optical fiber having a core region and a cladding surrounding the core region, and a micro-cavity having part of the cladding and the core region removed, wherein the micro-cavity is adapted to receive a light beam and separate the light beam into a first light beam that propagates through the micro-cavity in an unguided mode, and a second light beam that propagates through the core region in a guided mode.
Claims9
A single fiber Mach-Zehnder interferometer comprising:
- an optical fiber having a core region and a cladding surrounding the core region;
- and
- a micro-cavity having part of the cladding and the core region removed, the micro-cavity is directly exposed to external environment,
- wherein the micro-cavity is adapted to receive a light beam and separate the light beam into a first light beam that propagates through the micro-cavity in an unguided mode, and a second light beam that propagates through the core region in a guided mode.
A method of making a single fiber Mach-Zehnder interferometer using an optical fiber having a core region and a cladding surrounding the core region, the method comprising:
- creating a micro-cavity on the optical fiber with part of the cladding and the core region removed, the micro-cavity is directly exposed to external environment,
- wherein the micro-cavity is adapted to receive a light beam and separate the light beam into a first light beam that propagates through the micro-cavity in an unguided mode, and a second light beam that propagates through the core region in a guided mode.
