Single and Dual Photonic Jets With Tipped Waveguides: An Integral Approach

Single and dual photonic jets generated by weak multimode waveguides can be studied out rigorously by means of an integral equation. The latter can be obtained on the basis of a principle that resembles one of Mautz and Harrington's although the context is different. Comparison with finite difference time domain results showed overall good agreement, and because the method is fast, it can be used for optimization purposes. In particular, it permitted us to obtain dual photonic jets with beam separation as small as a wavelength.
