Two types of ultra-small silicon microring-based duobinary modulators are proposed and compared.Required drive voltage is as low as 0.77 volt. at 10 Gb/s. Extinction ratio is > 15 dB.
Cost-effective method for generating >20 GHz pulse trains using actively mode locking fiber ring laser
high-speed millimeter wave mode locking fiber laser Mach–Zehnder interferometer optical communications
2011/4/25
This study proposes a simple method to generate high-speed pulse of more than 20 GHz. Its cost performance ratio in an actively rational harmonic mode locking scheme is maximized when the multiplicati...
