Auto Bias Control Technique for Optical 16-QAM Transmitter with Asymmetric Bias Dithering

Not Accessible

Your library or personal account may give you access

Abstract

ABC (Auto Bias Control) technique for QAM (Quadrature Amplitude Modulation) transmitter is demonstrated. 16 QAM (10G baud) is generated and controlled using a single IQ modulator and asymmetric bias dithering technique. Measured penalty is 0.3dB.
