| Popis: | On-chip optical parametric gain was first demonstrated in a silicon waveguide using a pulsed pump source [1]. However, the realization of optical net-gain with a continuous-wave (CW) pump remains a challenge in integrated platforms. Highly nonlinear fibers can provide parametric gain with CW pump [2]. The key advantage of this low-loss platform is its long effective length L eff , which results in a huge nonlinear phase shift, Θ NL = γPL eff using moderate power levels, P, in spite of the relatively low nonlinear parameter γ. The question we address in this contribution is: How far are we from obtaining net gain in a CMOS-compatible platform under CW pumping? |
