We investigate by theory ultra broadband photon pair generation in graded index multimode optical fibers (GIMFs). It has been shown how the unique dispersive properties of GIMFs provide an opportunity to generate state engineered photon pairs. Our findings hint on interesting features such as:
- GIMFs provide can be used as an ultra tunable source of state engineered photon pairs.
- Quantum correlations are independent of fiber mode and group number and only depend on spectral separation from the pump.
- It is possible to simultaneously generate uncorrelated and correlated photon pair in the same fiber.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the conference proceedings. They include the speaker's narration along with a video recording of the presentation slides and animations. Many conference presentations also include full-text papers.
