Measurements of small-signal intensity modulation from direct-modulated distributed feedback (DFB) semiconductor lasers after propagation in dispersive fiber have previously been used to extract intrinsic laser chirp parameters such as linewidth enha

Linewidth and small-signal modulation response measurements are reported for room-temperature-operating microcavity two-dimensional photonic crystal lasers. The measured optical linewidth versus the output power was found to saturate at values on the

Mach–Zehnder interferometers were fabricated from suspended membrane photonic crystal waveguides. Transmission spectra were measured and device operation was shown to be in agreement with theoretical predictions.

We describe the demonstration of sapphire-bonded photonic crystal lasers operating under room temperature CW conditions and characterize the modal properties and small-signal modulation response of these lasers. In addition, we describe progress in p

The effect of transmission through a fiber Bragg grating on the relative intensity noise of semiconductor laser light is investigated. We first present a model of the grating as a linear frequency discriminator that exchanges correlated power between

We have demonstrated that transmission through a fiber grating can increase the system response of a directly modulated semiconductor laser by over 7 dB at all modulation frequencies up to 25 GHz. When combined with dispersive optical fiber, the grat

Summary form only given. The conversion of laser phase noise to intensity noise by the effect of group velocity dispersion (GVD) in a single-mode optical fiber is well-known. In fiber links such as analog "supertrunk" CATV links and digital dispersio

We demonstrate that the simple rate equations do not satisfactorily account for the chirp of DFB lasers and describe an experimental technique that determines it precisely using propagation in dispersive fiber. Implications for high-speed lightwave s

A new expansion for the Jones matrix of a transmission medium is used to describe high-order polarisation dispersion. Each term in the expansion is characterised by a pair of principal states and the corresponding dispersion parameters. With these de

An increase of the relative intensity noise of nearly single-mode distributed feedback lasers with respect to that predicted by single-mode theory after propagation in dispersive fiber at frequencies up to 5 Ghz has been measured. A simplified multim
