Double Sideband Suppressed Carrier Optical Modulator
Abstract
The development of a novel single-chip integrated optic double sideband suppressed carrier (DSSC) modulator on lithium niobate substrate for operation at 1300 and 1550 nm wavelengths is described in this report. This chip contains two Mach-Zehnder (m-z) and two phase modulator sections which are computer controlled for operation at the third-order intermodulation distortion point minimum. To assess insertion potential into microwave/millimeter wave (mW/mmW) systems, systems level performance characteristics of the DSSC has been investigated. Performance measures included but were not limited to measurement of IMD, harmonics, noise figure (NF), and phase drift. This data was used to determine the intercept point, spurious free dynamic range (SFDR), etc. To some extent environmental and operational effects were also studied. Additional investigation was conducted to look into alternative biasing schemes to improve or optimize performance of the DSSC. Experiments were performed to validate optimization and are reported here.
