Enchanced sensitivity coupled fiber-optic biosensor configurations |
June 13, 2006 |
| Coupled fiber-optic, evanescent-wave biosensors are improved through the use of configurations which adjust certain optical characteristics for enhanced sensitivity. In the preferred embodiment, this is carried out by inputting light into the coupler at either a different wavelength or |

Coupled capillary fiber based waveguide biosensor |
December 13, 2005 |
| An evanescent-wave optical biosensor includes a hollow optical waveguide, preferably in the form of a light-conductive capillary, surrounding a central waveguide preferably in the form of an optical fiber to create a sealed cavity. A source of optical energy as from a laser is directed i |

Single-and multi-mode configurations for fiber-optic-coupler biosensors |
August 2, 2005 |
| Single-mode and multi-mode fibers to achieve modal splitting and greater sensitivity in an optical fiber coupler for evanescent-wave biosensor applications. A source of light having multiple modes is coupled to the input to one of the multi-mode fibers, with the geometry of necked-down |
