This tutorial describes the transmission, group delay time and quadratic dispersion
properties of the four basic building blocs of optical filters built using ring resonators. These …

This book is all about integrated ring resonators made out of optical waveguides in various
materials for different applications. Integrated ring resonators are used to build optical filters …

A key device in all-optical networks is the optical filter. A ring resonator filter with an
integrated semiconductor optical amplifier (SOA) on the basis of GaInAsP-InP has been …

An all-optical reconfigurable logic operation essentially constitutes a key technology for
performing various processing tasks with ultrafast signal-processing technologies. We …

The filter response of single-ring resonators with integrated semiconductor optical amplifiers
based on GaInAsP-InP is presented. The devices with free spectral ranges of 25 and 50 GHz …

Microring resonators (MR) represent a class of filters with characteristics very similar to those
of Fabry–Perot filters. However, they offer the advantage that the injected and reflected …

In this paper, a simple but novel scheme for all optical clocked D flip flop based on single
micro-ring resonator with a feedback loop is proposed and prescribed. The GaAs-AlGaAs …

We propose and analyse a GaAs-based optical switch having a ring resonator configuration
which can switch optical telecommunication signals over the 1300 nm and 1500 nm bands …

We present a review of our work on ring lasers using passive waveguides and couplers
(directional and multimode interference) integrated with semiconductor optical amplifiers …

A monolithic single-mode GaInAsP-InP double microring resonator coupled laser is
demonstrated for the first time. The laser comprises two passive ring resonators …
