Creation and control of light soliton molecules a) Physical Sciences, ii)Physics, 4)Quantum Optics, Nonlinear Photonics

Abstract

In this project we have two scientific objectives: 1 - Create soliton molecules (SM) on demand using a fine control of the dispersion. Control directly the internal degrees of freedom such as time separation and relative phase of the SMs. 2 Ð Study how the dispersion affects different nonlinear dynamical regimes. Investigate if there is a direct and proportional cause and effect relation between dispersion changes and different soliton dynamic regimes. To achieve them we will need to have a fine control of the dispersion. First, we will use an Yb MLFL to generate solitons, soliton molecules and some dynamical regimes. This can be obtained by changing the laser cavity parameters such as polarization (pulse intensity) and dispersion. To have a fine control of the dispersion, we will put a SLM in the laser cavity. Our laser has a repetition rate of 130 MHz, with the dispersion compensation given by a pair of diffraction gratings. The SLM will be inserted after the grating pair, as shown in fig. 1. The SLM allows us to put different phase masks in order to control different spectral components of the laser. Then, the laser cavity needs to be aligned. After that, it is necessary to do a calibration of different phase masks and also to test its limits where the laser stops pulsing. Figure 1.
