A novel silicon microdisk modulator with "error-free" ∼3 femtojoule/bit modulation at 12.5Gbs has been demonstrated. Modulation with a 1 volt swing allows for compatibility with current and future digital logic CMOS electronics. ©2010 IEEE.

By comparing the frequency deviations of the TE and TM modes of identically designed silicon microdisk-resonators across a wafer, we demonstrate that layer thickness non-uniformity is the dominant cause of fabrication-induced microdisk-resonator frequency deviation. © 2009 Optical Society of America.

A new class of microphotonic-resonators, Adiabatic Resonant Microrings (ARMs), is introduced. The ARM resonator geometry enables heater elements to be formed within the resonator, simultaneously enabling record low-power (4.4μW/GHz) and record high-speed (1μs) thermal tuning. ©2009 Optical Society of America.

Microdisk resonators for use as low energy modulators in telecom and datacom applications have been fabricated using vertical PN junctions which operate in reverse bias. These devices have demonstrated the lowest energy/bit thus far. In this paper we show that the reverse biased PN junction diodes follow the analytical depletion approximation based on numerical simulation.

We demonstrate a 4μm silicon microdisk modulator with a power consumption of 85fJ/bit. The modulator utilizes a reverse-biased. vertical p-n junction to achieve 10Gb/s data transmission, with 3.5V drive voltage, BER<10-12, and without signal pre-emphasis. High-speed silicon bandpass switches are constructed from pairs of modulators. © 2008 IEEE Institute of Electrical and Electronics Engineers.

A novel fabrication strategy has produced optical microring-resonator-based thermal detectors. The detectors are based on the thermo-optic effect and are thermally isolated from a silicon wafer substrate so as to maximize the temperature excursion for a given amount of incident radiation and minimize the impact of thermal phonon noise. The combination of high-Q, thermal isolation, and lack of Johnson noise offers thermal microphotonic detectors the potential to achieve significantly greater room temperature sensitivity than standard bolometric techniques. Several batch fabrication strategies were investigated for producing thermal microphotonic detectors using waveguide materials such as LPCVD Silicon Nitride (Si3N4) on Oxide and Silicon on Insulator (SOI). Fabrication challenges and loss reduction strategies will be presented along with some initial infrared detection results.
