Intensity noise reduction effects by superimposed pulse modulation are theoretically
analyzed for LD inherent noise, feedback light noise, and modal noise. It is shown that noise …

This paper describes the improvement in mode partition noise characteristics when a laser
light is injected into a laser diode modulated at 400 Mbits/s. A single-mode fiber …

Laser phase noise conversion to intensity noise due to fiber chromatic dispersion is
analyzed by deriving the noise power spectral density. Theory predicts that the phase …

Semiconductor laser mode partition noise (LMPN) can impair analog optical systems, but
this phenomenon has not previously been well-characterized. Theoretical expressions for …

The relation between laser linewidth and modal noise was studied in a pulse frequency
modulation transmission system through employing a distributed feedback laser which …

A fiber-optic differential-delay-line structure converts the phase noise of its short coherence
source to intensity noise at its output. If this structure is followed by a similar system, intensity …

The dynamic range of fiber optic signal processors driven by relatively incoherent multimode
semiconductor lasers is shown to be severely limited by laser phase-induced noise. It is …

We report the first quantitative study of intensity noise induced in line-by-line pulse shaping
in response to time-varying changes in the comb frequency offset. Controllable comb …

The sensitivity of commercially available pigtailed laser diode modules to optical feedback,
in terms of laser relative intensity noise, is investigated. A pigtailed laser diode model which …

Phase-induced intensity noise in optical networks that employ directly modulated laser
sources is observed to be bit-sequence dependent. This dependence is explained by optical …
