Fiber optics for spin waves

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...

Fiber Fourier optics.

The Fourier transform of a coherent optical image can be evaluated physically by use of a single lens plus free-space propagation, thereby providing the basis for the field of Fourier optics. I point out that one can similarly evaluate the discrete Fourier transform of a sampled or pixelated optical array physically by passing the discrete array amplitudes through a network of single-mode fiber...

Infrared Fiber Optics

Infrared (IR) optical fibers may be defined as fiber optics transmitting radiation with wavelengths greater than approximately 2 μm. The first IR fibers were fabricated in the mid-1960’s from chalcogenide glasses such as arsenic trisulfide with losses in excess of 10 dB/m. During the mid-1970’s, the interest in developing an efficient and reliable IR fiber for short-haul applications increased ...
