Abstract
An integrated optical device comprising two arrayed waveguide gratings (AWGs) and an electrooptic modulator array is described. When used in conjunction with a broadband light source, the integrated optic device can provide multiple high data rate signals from a single optical light source. The first AWG spectrally slices the light from the broadband light source. Each optical signal is then modulated using an electrooptically-clad silica waveguide Mach-Zehnder interferometer. The second AWG multiplexes the modulated optical signals onto a single output fiber. The paper describes the design of the modulator-multiplexer circuit. Experimental results of the modulator portion of the circuit show the modulation of light at 1550 nm in a electrooptically-clad silica waveguide at data rates of 1 GB/s.
