Broadly tunable wideband optical single sideband generation using self-coupled silicon resonator

We propose and demonstrate a tunable broadband optical single sideband generation using self-coupled silicon micro-ring resonator. We exploit self-coupling in a ring cavity to generate tunable resonance splitting. Using the proposed device, single sideband with carrier signal is generated from a double sideband signal. Experimental verification of power fading free transmission through a 43 km signal mode optical fiber is achieved for an RF frequency range of 1-20 GHz, extendible to higher frequencies. We also achieved a spurious free dynamic range of > 99.9±1.05 dB.Hz^2/3 over the demonstrated frequency range. Furthermore, error-free data transmission of 1-12 Gbps over a 43 km fiber is also demonstrated with a detailed analysis of bit error rate as well.
