Fiber optics method for nanomaterials diagnostics

Self-assembled nanomaterials for nonlinear fiber optics and tunable plasmonics

As an amorphous material with full inversion symmetry, silica-based microstructures cannot possess significant secondorder nonlinearity. We recently developed a method that can potentially overcome this deficiency by coating a silica fiber taper with layers of radially aligned nonlinear molecules. The coating process can be accomplished through layerby-layer self-assembly, where the alignment o...

Disposable optics for microscopy diagnostics

The point-of-care testing (POCT) is having increasing role on modern health care systems due to a possibility to perform tests for patients conveniently and immediately. POCT includes lot of disposable devices because of the environment they are often used. For a disposable system to be reasonably utilized, it needs to be high in quality but low in price. Optics based POCT systems are interesti...

Fiber Optics

Dramatic improvements in the development of low-loss materials for optical fibers are responsible for the commercial viability of fiber-optic communications. Corning Incorporated pioneered the development and manufacture of ultra-low-loss glass fibers. C 0 R N I N G 272 Fundamentals of Photonics

Fiber-lasers for ultrafast optics

The current status of a fiber-based ultrafast technology is reviewed. Pulse generation techniques capable of producing femtosecond pulses are discussed. Here we describe passive and active–passive mode locking techniques as well as linear and nonlinear fiber amplifiers. Thirtyfemtosecond pulses may be generated directly from fiber oscillators or by implementing pulse compression techniques. The...
