A converter from a singlemode fiber to the fundamental mode of an OM2, OM3, OM4, or OM5 type multimode is presented and used transmit 100 GbE with no detected errors over 1600 m using commercial transceivers. The based on splicing short length few-mode between fiber. designed so that has good overlap To suppress any higher order modes in fiber, optimized bend stripper used. low loss 0.35 dB, lo...

We report on the experimental demonstration of a white-light supercontinuum generation in normally dispersive singlemode air-silica microstructured fiber. We demonstrate that the simultaneous excitation of the microstuctured fiber in its normal and anomalous dispersion regimes using the fundamental and second harmonic signals of a passively Q-switched microchip laser leads to a homogeneous supe...

The research has measured the landslide using a displacement sensor based on Glass Optical Fiber (GOF) and Time Domain Reflectometer (OTDR). manufacture process consists of various materials, structures, configurations, diameters, directions. is made GOF with single-mode structure single mode-multimode-Singlemode (SMS) structure. Each system given variety namely gamma, bowknot, three loops conf...

The frequency dynamics of gain-switched singlemode semiconductor lasers subject to optical injection is investigated. The requirements for low time jitter and reduced frequency chirp operation are studied as a function of the frequency mismatch between the master and slave lasers. Suppression of the power overshoot, typical during gain-switched operation, can be achieved for selected frequency ...

Traditionally, Raman spectroscopy is done in a specialized lab, with considerable requirements in terms of equipment, time and manual sampling of substances of interest. We present the modeling, the design and the fabrication process of a microfluidic device incorporation Raman spectroscopy, from which one enables confocal Raman measurements on-chip. The latter is fabricated using ultra precisi...
