Characteristics of quantum well infrared photodetectors
... IV and V! when the first term in the left-hand side of ~2! is negligible, this equation becomes linear with respect to S n and the average electron sheet density is determined by the average capture parameter. Thus, expressions derived below are strict even in the case of b dependent on the local el ...

... This classical-physics relationship, which leads to the quantum-mechanical time–energy uncertainty principle, has several important consequences in the field of ultrashort light pulses. – In order to produce a light pulse with a given duration it is necessary to use a broad enough spectral bandwidth. ...

High accuracy ranging with Yb -doped fiber-ring frequency
... In chirped-pulse interferometry the measurement accuracy is inversely proportional to the tuning range of the laser frequency. As an example, using continuously tunable laser diodes with a tuning range of 500 GHz, a spectral width of 25 MHz and a repetition time 10 ls (a chirp rate cc = 5 · 1016), o ...
