Nettet5. apr. 2004 · Abstract: A new method for the measurement of the linewidth enhancement factor of semiconductor lasers is presented, based on the interferometric self-mixing effect. It is a fast and easy to perform method that does not require radio frequency nor optical spectrum measurements. A small fraction of the emitted light is backreflected into the … NettetBy combining the treatment line with a 4.2m SMMMS line and a 3.2m SSMMS, designed with medical fabrics in mind, SAAF can offer total flexibility across line width and …

Nettet8. aug. 2012 · We report on measurements of the linewidth Δf of terahertz radiation emitted from intrinsic Josephson junction stacks, using a Nb/AlN/NbN integrated receiver for detection. Previous resolution-limited measurements indicated that Δf may be below 1 GHz—much smaller than expected from a purely cavity-induced synchronization.
