Patent number: 10359574Abstract: Systems and methods are provided for mechanically encapsulating an infrared transmitting optical fiber, removing any power coupled to the cladding of the infrared optical fiber, and bridging the thermal properties between the optical fiber and the mechanical ferrule used. Embodiments of the present disclosure have several advantages over prior systems. For example, in an embodiment, the transmitting ferrule does not require epoxy to mount the fiber to the ferrule, isolates the front face of the fiber, and allows for high power to be incident on the connector without damage by reducing the thermal induced stress and managing any stray light coupled to the core.Type: GrantFiled: June 5, 2018Date of Patent: July 23, 2019Assignee: The United States of America, as represented by the Secretary of the NavyInventors: Rafael R.

Patent number: 9577401Abstract: Fiber optic amplification in a spectrum of infrared electromagnetic radiation is achieved by creating a chalcogenide photonic crystal fiber (PCF) structure having a radially varying pitch. A chalcogenide PCF system can be tuned during fabrication of the chalcogenide PCF structure, by controlling, the size of the core, the size of the cladding, and the hole size to pitch ratio of the chalcogenide PCF structure and tuned during exercising of the chalcogenide PCF system with pump laser and signal waves, by changing the wavelength of either the pump laser wave or the signal wave, maximization of nonlinear conversion of the chalcogenide PCF, efficient parametric conversion with low peak power pulses of continuous wave laser sources, and minimization of power penalties and minimization of the need for amplification and regeneration of pulse transmissions over the length of the fiber, based on a dispersion factor.Type: GrantFiled: July 31, 2015Date of Patent: February 21, 2017Assignee: The United States of America, as represented by the Secretary of the NavyInventors: Leslie Brandon Shaw, Jasbinder S.
