We have determined the kinetic response of an evanescent wave optical fibre immunosensor and its absolute sensitivity. Using both kinetic methods and optical determinations of bound antigen, we infer that there are 2·4 × 10 11 active antibodies per

A powerful and increasingly common method to mode-lock a variety of lasers is additive pulse mode-locking (APM). In this technique, a nonlinear medium is placed in an external cavity which is coupled to the main laser cavity. As a result of interfere

Observation of polarization instabilities and modulational gain in a low-birefringence optical fiber
Publikováno v:
Optics letters. 15(6)
Intense linearly polarized light has been used to observe polarization instabilities due to the optical Kerr effect in a low-birefringence optical fiber. Near the onset of instability small intensity modulations are amplified and a sixfold increase i

A nonlinear periodic structure can convert an input continuous wave beam into a train of pulses. This modulational instability implies that the nonlinear spatial resonance (‘‘gap solitons’’) of distributed feedback structures are generally un

We have used an evanescently excited fiber optic immunoassay in order to study the kinetic response of an immunosens anddetermine its absolute sensitivity. We have estimated that when binding sites are saturated approximately 10" antigen are1xind to

When birefringence induced through the optical Kerr effect in an unperturbed, weakly birefringent fiber is comparable with the natural fiber birefringence, polarization instability and asymmetry between the fast and slow fiber axes arise. A signature

Polarization instabilities in a weakly birefringent optical fiber with low twist lead to experimentally observed modulational gain and asymmetry between the principal fiber axes.

Observation of spectral broadening caused by self-phase modulation in highly multimode optical fiber

Applied Optics. 36:617
We observed spectral broadening caused by self-phase modulation in 400- and 600-microm core diameter fibers using amplified, Q-switched, Nd:YAG laser pulses with peak powers to 150 kW. The degree of spectral broadening was not dependent linearly on t

The fast-axis polarization instability arises in a weakly birefringent fiber as a result of competition between the natural fiber birefringence and the nonlinear ellipse rotation. Direct observation of the fast-axis polarization instability is report
