LINEARIZATION OF A BROADBAND ANALOG LINK USING TWO WAVELENGTHS |
摘要 |
A modulator driven by an externally applied RF signal intensity modulates carrier signals at different wavelengths. The modulator bias voltage and the ratio of the optical powers of the carrier signals are selected to minimize second and third order distortion. The modulated signals are separately detected and the resulting electrical signals are combined to yield a linearized representation of the RF signal. An electro-optic device capable of wavelength multiplexing and demultiplexing can independently and jointly control the bias voltages for the transfer functions of the two carrier signals.
