Paper Abstract

The influence of regular longitudinally inhomogeneous sections of the waveguides on the level of modal noise, and its dependence on the degree of both spatial and temporal coherence of the radiation source are investigated using the mode approach. The way to reduce modal noise at the joints of waveguides with matching sections between the waveguides is proposed. It is shown that under the matching condition the complete suppression of modal noise due to the joint is possible. A way to reduce modal noise by using random microlens arrays and holographic diffusers is also proposed.
