Optical signal processing techniques employ a wide range of devices and various nonlinearities to achieve multiple network functionalities. The choice of nonlinearity can also impact the relative efficiency, both in terms of energy and material consumption, of the signal processing function being implemented. Techniques for some of the important functionalities, wavelength multicasting, wavelength-division...
We propose a compact silicon microring-based analog modulator for generation of 10-GHz sub-octave analog signals, which exhibit high optical modulation-index of up to 46% and carrier-to-noise ratio (CNR) of 57 dB. In fiber transmission, the CNR can be improved further by 10 dB with chromatic dispersion.
