Monolithically Integrated Wavelength-Routing Switch Using Tunable Wavelength Converters with Double-Ring-Resonator Tunable Lasers

We present an 8 × 8 wavelength-routing switch (WRS) that monolithically integrates tunable wavelength converters (TWCs) and an 8 × 8 arrayed-waveguide grating. The TWC consists of a double-ringresonator tunable laser (DRR TL) allowing rapid and stable switching and a semiconductor-optical-amplifier-based optical gate. Two different types of dry-etched mirrors form the laser cavity of the DRR TL...

Wavelength Tunable Laser with Silica-Waveguide Ring Resonators

We have proposed a tunable laser with silica-waveguide ring resonators. In this tunable laser, a semiconductor optical amplifier was passively aligned and mounted onto a silica-waveguide substrate. The ring resonators can be tuned by controlling their temperatures using the thermo optic heaters formed on them, and there are no mechanically moving parts. Thus, they are sufficiently stable and re...

Wavelength Swapping using Tunable Lasers for Fractional λ Switching

Lambda Switching (FλS) is a novel proposal for the management of all-optical networks with sub-wavelength provisioning capability. The unique characteristic of FλS is the utilization of the UTC (coordinated universal time) for alignment and switching. Several central research issues are still open in FλS and need to be formally defined and analyzed. Within the scope of this paper, we introduce ...
