WebAbstract: We have developed ultrashort pulse generation by the electrooptic modulation method, where continuous-wave laser light of any wavelength can be converted to trains of ultrashort optical pulses with a variable and high repetition frequency by means of an electrooptic phase modulator for the generation of deeply chirped light, and an optical … Webgroup velocity to vary, it is classified as material dispersion. The group delay Tg is given by the product of the propagation distance z by the first frequency-derivative of the …
WebThe delay component is important because, unlike the Isolator, it will calculate without having a signal at the input port. If the laser and the delay calculate, the Isolator will have signals available at both input ports. Run the simulation again and open the visualizers.
