Wireless coverage of the end-user domain, be it outdoors or indoors (in-building), is poised
to become an essential part of broadband communication networks. In order to offer …

For short-reach applications, 40-Gb/s directly modulated semiconductor lasers enable high-
capacity transmission with a simple and low-cost configuration. We investigated the chirp …

We investigate the use of a 1060 nm single-mode vertical-cavity surface-emitting laser
(VCSEL) and a 1060 nm single-mode fiber as a competitive single-mode technology for cost …

We report on results from the characterization of the frequency chirp characteristics of
distributed feedback (DFB) lasers under direct modulation conditions. Parameters …

Chirp properties induced by semiconductor optical amplifiers (SOAs) are investigated by a
simple chirp measurement method using an optical bandpass filter. We measure the chirp …

A new method for measuring time-resolved frequency chirp of a modulated light source at
high bit rate is presented. This method uses a Mach-Zehnder interferometer as an optical …

We present a novel implementation of the “phase reconstruction using optical ultra fast
differentiation”(PROUD) technique and apply it to characterize the time resolved chirp of a …

To enable optimum network transmission, the ideal is to launch as high laser power as
possible into the optical fiber, to overcome the effects of fiber attenuation and maintain an …

Optical communications has experienced a rapid development during the last decade. More
bandwidth can be acquired by decreasing the spacing of the optical channels or by …

Optical spectrum analysis and polarization analysis are not generally related by
conventional wisdom. In this paper, we show that the spectrum of a light beam can be …
