To this end, we examine the impact of several types of loss on the total amplification of the Stokes wave that can be achieved via SBS. We account for linear loss and nonlinear loss of third order (two-photon absorption, 2PA) and fifth order, most notably 2PA-induced free carrier absorption (FCA). From this, we derive an upper bound for the output power of continuous-wave Brillouin-lasers and show that the optimal operating conditions and maximal realisable Stokes amplification of any given waveguide structure are determined by a dimensionless parameter ℱ involving the SBS-gain and all loss parameters. We provide simple expressions for optimal pump power, waveguide length and realisable amplification and demonstrate their utility in two example systems. Notably, we find that 2PA-induced FCA is a serious limitation to SBS in silicon and germanium for wavelengths shorter than 2200nm and 3600nm, respectively. In contrast, three-photon absorption is of no practical significance.}, language = {en} } @article{LedentsovJrShchukinLedentsovJretal.2016, author = {Ledentsov, Jr., Nikolay and Shchukin, Vitaly and Ledentsov, Jr., Nikolay and Kropp, J{\"o}rg-R. and Burger, Sven and Schmidt, Frank}, title = {Direct Evidence of the Leaky Emission in Oxide-Confined Vertical Cavity Lasers}, volume = {52}, journal = {IEEE J.
