Analysis and simple tuning scheme of asymmetric Y-lasers

We present an analysis of interferometric lasers in Mach-Zehnder configuration with emphasis on the recently realized asymmetric Y-laser, leading to simple design and tuning rules. By tailoring the Mach-Zehnder (MZ) filter function we obtain a large variety of designable channel spacings together with improved sidemode suppression and easy access for wavelength division multiplexing (WDM) functions and wavelength conversion.<
