Grating Cavity Laser Integrated Mach-Zehnder Interferometers for Tunable Wavelength Conversion

摘要

A grating cavity laser and a Mach-Zehnder interferometer are monolithically integrated for a tunable wavelength converter, consisting of semiconductor optical amplifiers, a deeply etched diffraction grating, a beam deflector, and passive waveguides with alternating structures. The interferometers for wavelength conversion have demonstrated at 2.5 Gb/s using the probe source from the device with an eight channel grating cavity laser which can provide wavelength tuning range of 43 nm with an SMSR > 40 dB.
