Carrier-depletion based silicon waveguide resonant cavity modulator with integrated optical power monitor Universiteit Gent
Silicon carrier-depletion microring modulator is a key component in optical interconnect systems. Due to its resonance nature, the microring modulator has the advantages of compact size, low power consumption, low driving voltage, and so on. However, a drawback of this structure is that the optical modulation occurs only within a narrow wavelength range near the resonance. A typical optical bandwidth of effective modulation is less than 0.1 nm. On the other hand, the silicon waveguide is susceptible to the temperature variation. A ambient temperature change of 1 K will shift the resonance ...
