In this paper, we demonstrate optical injection locking in the 2 µm wavelength region between two discrete semiconductor lasers. We will highlight how such behaviour can be used as a key enabling technology in this new wavelength window, motivated by system improvements such as better filtering and linewidth reduction for advanced modulation formats.
A universal simulation model for rare earth doped cw fibre lasers is presented. The model is based on generic rate and gain equations and therefore is very compact. It can be used for any fibre doped with one or several rare earth ions. The model allows for spectral simulations as well as radial discretization of the fibre. An algorithm was developed which optimizes the longitudinal fibre segmentation...
We report on our direct experimental observation of a new regime of operation of passively mode-locked fibre lasers where the laser oscillator generates pulsating solitons with extreme ratios of maximal to minimal intensities in each period of pulsations. The soliton spectra also experience large periodic broadening and compression. Spatio-temporal intensity and dispersive Fourier-transformation measurements...
