WebWe would like to show you a description here but the site won’t allow us. WebOptical intensities with the meaning as used in optical physics are relevant in various situations: In conjunction with transition cross-sections, intensities govern the rates of optical transitions, e.g. in laser gain medium. Strong saturation of an optical transition in the steady state occurs when the intensity exceeds the saturation intensity.

WebWhile gold gratings that support only m = –1 and 0 orders typically achieve DE > 90%, they have the lowest efficiency of the three types primarily due to absorption of light in the gold. While metals can make excellent mirrors, there is always some absorption. Scattering can also play a role when the gold surface exhibits significant roughness. WebTwo significant features to note from both the curve and the equation are that the photogenerated current (Ip)is additive to the diode current, and the dark current is merely the diode's reverse leakage current. Finally, the detector shunt resistance is the slope of the I-Vcurve (dV/dI) evaluated atV= 0. Photodiode Operation w.wang
