Abstract
We report a novel hybrid integrated optic device consisting of AlGaInAs/InP electroabsorption modulators and a four-arm silica-on-silicon planar lightwave circuit optical interferometer. The device is designed for generation of high spectral efficiency optical modulation formats. We demonstrate generation of 21.4 Gb/s quadrature phase shift keyed optical signals with electrical data drives of 2Vpp amplitudes, achieving a bit error rate of 10 -9 with the required optical signal to noise ratio of ∼18 dB in a 0.1 nm resolution bandwidth.
