A hybrid optoelectronic integrated circuit (OEIC) comprising a laser diode (LD) driven by a resonant tunnelling diode (RTD) can output various optical and electrical signal patterns that include self-sustained oscillations, sub-harmonic and harmonic locking and unlocked signals, with potential applications in optical communication systems.
An all solid-state kicker pulser for a high current induction accelerator (the Dual-Axis Radiographic Hydrodynamic Test facility DARHT-2) has been designed and fabricated. This kicker pulser uses multiple solid state modulators stacked in an inductive-adder configuration. Each modulator is comprised of multiple metal-oxide-semiconductor field-effect… (More)
A new method to measure thin oxide thickness in CMOS technology is presented. Using a constant Fowler-Nordheim tunneling current through the gate oxide, the tunnel voltage across the oxide has been shown to be linearly proportional to the gate oxide thickness. The proposed tunnel voltage method can detect oxide thickness variation as small as 0.1 /spl… (More)
