20090320526 | Pre-Form For And Methods Of Forming A Hollow-Core Slotted PBG Optical Fiber For An Environmental Sensor - A preform for forming a hollow-core, slotted photonic band-gap (PBG) optical fiber for use in an environmental sensor, and methods of forming such a fiber using the preform are disclosed. The preform comprises a slotted cladding tube that surrounds a slotted, hollow-core PBG cane. The slots in the cladding tube and PBG cane are longitudinally formed and substantially aligned with each other. When the preform is drawn, the slots merge to form an elongated side opening or slot in the resulting hollow-core PBG fiber. In one case, the slot reaches the hollow core upon drawing, while in another case a second step is used to extend the slot to connect to the hollow core. The fiber is used to form an environmental sensor for sensing the presence of a target substance in an environment. The slot formed in the PBG region of the fiber forms a ridge waveguide wherein a portion of the light that otherwise is confined to the hollow core as a bound mode travels in the slot. The target substance affects the light traveling in the fiber, allowing for the target substance to be detected. | 12-31-2009 |
20110265520 | Methods For Determining The Rotational Characteristics Of An Optical Fiber - A method for determining a rotational characteristic of an optical fiber is disclosed. The method includes forming an orientation registration feature in an optical fiber preform and drawing an optical fiber from the preform such that the orientation registration feature formed in the optical fiber preform is imparted to the optical fiber. The optical fiber is then rotated about a longitudinal axis and the direction of rotation is periodically reversed. An orientation signal of the optical fiber is determined based on a position of the orientation registration feature as the optical fiber is rotated. A rotational characteristic of the optical fiber is then determined based on the orientation signal. | 11-03-2011 |
