Abstract
A fiber-end surface structuring chamber or system having a main body with multiple ports including a fiber-holder port, a process port that is either a stamp/shim holder port or a plasma etching enabler port, an evacuation port, a gas delivery port, and one or more observation ports, where the fiber-end surface structuring system forms structures directly into the end of the fiber to enhance transmission of light over a wide range of wavelengths and increase the laser damage threshold.
Claims14
A fiber-end surface structuring system, comprising:
- a main body comprising multiple ports;
- a fiber-holder port comprising a fiber-holder port accessory that comprises means to attach an optical fiber such that the fiber extends out of the fiber-holder port from between 1 and 2000 microns;
- a process port comprising a process port accessory that comprises means to mount a patterned shim and a laser delivery fiber mount, wherein the shim can be moved, tilted, or both with respect to the fiber;
- an evacuation port;
- a gas delivery port;
- and
- one or more observation ports;
- wherein said fiber-end surface structuring system forms structures directly into the end of the fiber.
A fiber-end surface structuring system, comprising:
- a main body comprising multiple ports;
- a fiber-holder port comprising a fiber-holder port accessory that comprises a connector to attach an optical fiber such that the top surface of the connector is flush with the fiber-holder port accessory or below the fiber-holder port accessory by less than 250 microns;
- a process port comprising a process port accessory that comprises a plasma gas delivery system and an electrode to generate and sustain a plasma;
- and
- an evacuation port.
