We report on a compact optical frequency comb, operating in the wavelength range from 670 to 1500 nm, based diode-pumped low-noise femtosecond Yb:CALGO amplified laser system. Both carrier-envelope offset and repetition rate are phase-locked reference synthesizers. A full characterization of terms stability, phase noise analysis, beating against single-frequency non-planar ring oscillator Nd:YA...

The modulation response, relative intensity noise (RIN) and frequency noise (FN) characteristics of quantum dot (QD) lasers are investigated theoretically in the presence of an external optical beam. Using small signal analysis of the rate equations for carriers and photons, it is demonstrated that by injecting excess carriers into the QDs excited state through optical pumping, the modulation r...

In this paper, a new algorithm for system identification based on frequency response is presented. In this method, given a set of magnitudes and phases of the system transfer function in a set of discrete frequencies, a system of linear equations is derived which has a unique and exact solution for the coefficients of the transfer function provided that the data is noise-free and the degrees of...
