Sound wave coupling enables all-silicon laser

Yale scientists have uses sound waves to amplify light in a new type of silicon laser for photonic ICs, side-stepping the problem of silicon’s indirect bandgap. “Silicon’s intrinsic properties, although very useful for many chip-scale optical technologies, make it extremely difficult to generate laser light using electrical current,” said Yale scientist Nils Otterstrom. “It’s a ...

Frequency hopping once per bit foils hackers

MIT researchers have developed a novel transmitter that frequency hops for each individual 1 or 0 bit of a data packet – so once per microsecond for 1Mbit/s, “which is fast enough to thwart even the quickest hackers”, according to MIT. The system can protect against selective jamming. For example, explained the University, Bluetooth LE ...

Toshiba MOSFETs have active-clamp structure

Toshiba is in volume production of MOSFETs that incorporate an active-clamp structure with a built-in diode between the drain and gate terminals. With the requirement for a minimum of external components the single SSM3K357R and the dual SSM6N357R are suited to drive inductive loads, such as mechanical relays or solenoids. The new 357 series protects ...

ST software can implement TCPM on any STM32 MCU.

ST has introduced new software for implementing a Type-C Port Manager (TCPM) on any general-purpose STM32 microcontroller. Compliant with the USB TCPCi specification, and designed to manage a separate single- or multi-port TCPC chip, ST’s X-CUBE-USB-PD stack implements the protocol layer and policy engine of the USB Power Delivery Specification (USB-PD 3.0 v1.1). The stack ...
