One of the attractive features of single mode waveguides is their ability to filter the spatial field distribution. All the wavefront aberrations only result in a photometric fluctuation easy to monitor. It results in a very good calibration of the interferometric data as firstly demonstrated by FLUOR, as seen in Fig. 8 (Coude du Foresto et al., 1998). Nevertheless, care has to be taken to keep in mind that turbulence may have a spectral selectivity in the launching pro-... 

The CEM Discover platform, introduced in 2001, offers a single-mode instrument based on the self-tuning circular waveguide technique (see Fig. 3.3). This concept allows for derivatization of the reactor to accommodate additional application-specific modules to address other common laboratory objectives. While the Discover ... 

An optical MNF is a waveguide that transmits light. Generally, an MNF is a multimode waveguide. In this chapter, we primarily consider single mode MNFs, which support the fundamental mode only. The diameter of a single mode MNF is...

Nonconventional fluorimeters and sensors that incorporate optical waveguide coupling possess less optical attenuation in the near-IR as compared with the UV/vis-ible because of the reduction in Rayleigh scattering. The temporal dispersion is also reduced in the near-IR for the same reason, e.g., 80 psec/nm/km at 900 nm as compared with 1 nsec/nm/km at 400 nm for a single-mode fiber.

In papers , unsteady-state regime arising upon propagation of the stationary fundamental mode from linear to nonlinear section of a single-mode step-index waveguide was studied via numerical modeling. It was shown that the stationary solution to the paraxial nonlinear wave equation (2.9) at some distance from the end of a nonlinear waveguide has the form of a transversely stable distribution ( nonlinear mode ) dependent on the field intensity, with a width smaller than that of the initial linear distribution.
