An experimental study of low-frequency amplitude noise in a fibre Bragg grating laser diode

We have studied the amplitude noise in a fibre Bragg grating laser diode. It has been shown that discontinuities in noise characteristics correlate with those in the power-current and spectral characteristics of the laser diode, whereas the noise characteristics of the pump source have no such disco...

Zusammenfassung:We have studied the amplitude noise in a fibre Bragg grating laser diode. It has been shown that discontinuities in noise characteristics correlate with those in the power-current and spectral characteristics of the laser diode, whereas the noise characteristics of the pump source have no such discontinuities. The highest noise level has been observed at pump currents corresponding to concurrent generation of two longitudinal modes.
