Abstract :
A micro embedded ring resonator modulator using quantum confined stark effect (QCSE) has been modeled and studied in this paper. Semi analytical design methods for various components like bend, coupler, and the whole embedded ring have been used here. Time domain and frequency domain analysis methods have been developed and studied. Using these methods a 50 Gbps, 11 dB extinction ratio, 5 μm outer radius embedded ring, QCSE tuned optical modulator design has been proposed.
