A Lightwave Energy-Efficient Datacenter (LEED) is described that consists of: 1) A novel optically-switched datacenter architecture, 2) a "Rotor" optical switch that can reconfigure a network topology in less than 20 microseconds, and 3) Enhanced lin

We present a novel frequency tracking method that exploits the dynamics of injection locking in a quadrature ring oscillator to increase the effective locking range from 5% (7–7.4 GHz) to 90% (4–11 GHz). The quadrature phase error between I and Q

Integrating optical receivers based on double-sampling architecture exhibit a low-power alternative to those designed around transimpedance amplifiers (TIA). In this paper, we present a 3D-integrated CMOS/silicon-photonic optical receiver. The receiv

In this work, a CMOS-SiPh optical transmitter based on carrier-injection ring modulators is presented. It features a novel low-power switched-capacitor-based pre-emphasis that effectively compensates the modulator bandwidth limitation. A wavelength s

We present a scheme for thermal stabilization of micro-ring resonator modulators through direct measurement of ring temperature using a monolithic PTAT temperature sensor. The measured temperature is used in a feedback loop to adjust the thermal tune

We present a differential ring modulator that breaks the optical bandwidth/quality factor trade-off known to limit the speed of high-Q ring modulators. This structure maintains a constant energy in the ring to avoid pattern-dependent power droop.

With continuous demand for higher bandwidth chip-to-chip communication, signaling over wires has become extremely challenging [1]. Optical signaling is an attractive alternative due to its small frequency-dependent loss and higher bandwidth. Recent a

Modern SoC systems impose stringent requirements on on-chip clock generation and distribution. Ring-oscillator (RO) based injection-locked (IL) clocking has been used in the past [1] to provide a low-power, low-area and low-jitter solution. Ring-base
