Apparatus and methods for stabilization and control of fiber devices and fiber devices including the same

A method of fabricating a photonic device, comprising:

• disposing at least one in-fiber device in or on a substrate;
• operationally coupling at least one sensor to the in-fiber device;
• operationally coupling at least one transducer to the in-fiber device;
• and
• operationally coupling feedback circuitry to the sensor and the transducer.

A system, comprising:

• an input port and an output port disposed on a substrate;
• a splitter/coupler disposed on the substrate and operationally coupled to the input port and output port;
• a first leg of a fiber Bragg grating-based Michelson interferometer disposed on the substrate and coupled to the splitter/coupler, a first set of control elements operationally coupled to the first leg;
• and
• a second leg of the fiber Bragg grating-based Michelson interferometer disposed on the substrate and coupled to the splitter/coupler, second set of control elements operationally coupled to the second leg.

A system, comprising:

• an input port, an add port, a drop port, and an output port each disposed on a substrate;
• a first splitter/coupler disposed on the substrate and operationally coupled to the input port and drop port;
• a second splitter/coupler disposed on the substrate and operationally coupled to the add port and output port
• a first leg and a second leg of a fiber Bragg grating-based Mach-Zehnder interferometer disposed on the substrate and coupled between the first and second splitter/couplers;
• and
• a first set and a second set of control elements operationally coupled to the first and second legs, respectively.
