Die Daseinsberechtigung der optischen Nachrichtentechnik ist selbst in einer Welt, die der
Technik latent zweifelnd gegenübersteht, einsehbar zu begründen: Sie schafft …

Recent progress in the dynamic single-mode (DSM) semiconductor lasers in the wavelength
of 1.5-1.6\mu m are reviewed and the basic principle of DSM operation is given. Study of the …

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 …

This review discusses the requirements and constraints on components for long-wavelength
monomode systems. In particular it critically reviews the current status of fibre, splicing …

Publisher Summary This chapter discusses the sources of noise in receivers employing
either p–i–n or avalanche photodiodes (APDs) and compares the sensitivities that can be …

This paper presents the theoretical and experimental results of a study on laser diode mode
partition noise. Laser diode mode partition noise is evaluated by mode partition constants …
