We numerically study the supercontinuum (SC) generation in a six modes photonic crystal fiber (PCF). By solving the multimode generalised Schrdinger equation, we demonstrate the generation of SC by initially exciting the fundamental mode or one of the higher order modes and then observe the energy transfer to the other high order modes. We analyze the energy transfer between degenerate modes during propagation through the few mode PCF. A detailed investigation of the nonlinear effects on the SC process through linear and nonlinear coupling is provided which confirms the energy transfer between optical degenerate modes during propagation inside the few- mode fiber.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for 2018 presentations, with transcripts for prior recordings added daily.
