The increasing demand for high bandwidth interconnection between integrated circuits requires large numbers of I/Os per chip as well as high data rates per I/O. Key limitations in meeting these requirements include channel characteristics and I/O power consumption. Using receiver and transmitter equalization can greatly improve the link performance.
As the resonance wavelength of micro-ring modulators is susceptible to temperature fluctuations, they require thermal tuning. The power consumed by wavelength stabilization circuitry is often higher than the transmitter itself. In this project a monolithic PTAT temperature sensor is proposed for low-power thermal stabilization of micro-ring resonator modulators through direct measurement of temperature.

In design of Micro-ring modulators it is desirable to have high-Q rings since for a given extinction ratio a higher Q results in better energy efficiency. However, there is a trade-off between the Q of the ring resonator modulator and its optical bandwidth. In this project we propose a new structure is proposed that breaks the optical bandwidth/quality factor trade-off known to limit the speed of high-Q micro-ring modulators. This structure, called the “differential ring modulator”, maintains a constant energy in the ring to avoid pattern-dependent power droop.
