| Popis: | We fabricated a slow-light Bragg reflector waveguide modulator and carried out both static and dynamic characterizations on this compact device. Extinction ratios of over 8 dB were obtained with low voltage swing such as 0.5 V. We demonstrated a 3-dB modulation bandwidth over 13 GHz in small-signal response characterization on a 35- μm-long device, which has a parasitic capacitance of 0.4 pF. Through further reducing the device length and achieving impedance matching, the result reveals its potential in reaching ultra-high modulation bandwidth over 100 GHz. Ultra-low power consumption much i100 fJ/bit is prospective thanks to the device's low voltage swing. |
