The availability of fiber combiners has been essential to the wide deployment of robust fiber lasers in the market. Some standard parts have emerged in larger volume, but new designs involving both different processes and different fiber configurations are being proposed to the market, offering novel or improved specifications. We will present some of those new designs involving true signal fiber feed-throughs and better return loss and isolation properties. The new fabrication process also allows more latitude in selecting the number of input pump fibers and is independent of the signal fiber's internal structure. © 2010 Copyright SPIE - The International Society for Optical Engineering.

The fiber optic assembly can include two fiber optic breadboards hinged to one another along a coinciding hinge axis. Each one of the fiber optic breadboards can have a flat body having two faces and lateral edges, one of which running alongside the hinge axis, and can have a tessellation of tray locations each having a tray attachment. The fiber optic assembly can also include a plurality of fiber optic trays each having a body having a base attachable to at least one of said tray attachments, the body having a size and shape associated to one of a single one of said tray locations and a plurality of adjacent ones of said tray locations on one of said at least one fiber optic breadboards, and having a structure by which an optical fiber having a critical radius of curvature can be confined within at least one optical fiber path.

The fiber optic hinge can mechanically connect a first fiber optic tray and a second fiber optic tray of a fiber optic device, while providing an optical fiber path extending continuously through the first and second hinge members.

We present a double-clad fiber coupler (DCFC) for use in endoscopy to reduce speckle contrast, increase signal collection and depth of field. The DCFC is made by fusing and tapering two all silica doubleclad fiber (DCF) and allows achromatic transmission of >95% of core illumination (1265nm - 1325nm) as well as collection of >42% of inner cladding diffuse light. Its potential for endoscopy is demonstrated in a spectrally encoded imaging setup which shows speckle reduction by a factor 5, increased signal collection by a factor 9 and enhanced depth of field by 1.8 times. Separation by the DCFC of single- and multi-mode signals allows combining low-speckle reflectance images (25.5 fps) with interferometrically measured depth profiles (post-processed) for of small three-dimensional (3D) features through an all-fiber low loss instrument. ©2010 Optical Society of America.

We developed a discrete master equation describing pulse propagation through the different components of dispersion-tuned fiber lasers, which cannot be achieved using average models. The model is validated through numerical simulations and experimental data. © 2011 Optical Society of America. Source
