Interferometer utilizing superfluorescent optical source

摘要: An improved broadband light source for a Sagnac interferometer includes waveguide (110), such as fluorescent optical fiber, that is pumped by pump (120) with sufficient intensity to generate temporally incoherent light. The fiber (110) has first and second ends, one end being an input of the (110). provided at output interferometer. In order prevent laser oscillations between interferometer, formed so reflections. from comprises only initially propagates toward embodiment coupled into in direction it travels away towards end. alternative embodiment, doubly clad having acceptance region introduced aperture window two regions can be angle without requiring reflective surface
