Optical gain
WebDot Gain, as measured and calculated by the densitometer, includes both mechanical gain (growth of the physical half-tone dot) and optical gain (how the dot appears to the human eye, due to the refraction of light on the substrate). Mechanical dot gain is measured using a microscope or magnifier to eliminate the effect of optical dot gain. WebWe observe for the first time net continuous wave optical gain in a low loss silicon-on-insulator waveguide based on stimulated Raman scattering. We show that nonlinear optical loss due to two-photon absorption induced free carrier absorption can be significantly reduced by introducing a reverse biased p-i-n diode in the waveguide. For a 4.8 cm long …
