POET’s co-packaging electronics and optics in a single Multi-Chip Module (MCM) is based on its previously announced Dielectric Waveguide technology. POET’s Optical Interposer provides the ability to run electrical and optical interconnections side-by-side on the same interposer chip at a micrometre scale.The company believes its Optical Interposer Platform targeting 100G transceiver applications is readily scalable to 200G and 400G transceiver products with minimal incremental cost. Importantly, the scalable architecture (in reach and speed) of this innovative platform has the potential to provide POET with a highly differentiated competitive advantage in leading-edge data communication transceiver products.The platform technology is applicable to both GaAs and InP based optical components. Optical engines for single mode transceiver modules represent the initial high-volume application for POET’s Optical Interposers.

With funding assistance from PowerAmerica, Wolfspeed developed first-of-its-kind SiC power modules for 3.3 kV and 10 kV applications. According to the company, this is the first SiC power module at these voltage levels to use exclusively the MOSFET built-in body diode as the anti-parallel rectifier. A built-in diode has numerous advantages over an external and additional diode device. The built-in diode or 'body diode' design maximises the performance of SiC MOSFET modules by freeing up space in the power module, allowing for more power capability and therefore increased performance in a smaller space. It also makes assembling a power module easier, boosting long-term reliability and optimising costs.

Dowa Electronics Materials successfully developed a deep ultraviolet LED chip, with an output power of 90mW, with a peak wavelength of 310 nm, and dimensions of 1 mm × 1 mm.Deep ultraviolet lights with a wavelength of 310 nm are used for curing and skin therapy. Replacing conventional mercury and excimer lamps with these LEDs enables equipment to be smaller and mercury-free. With the advantages of long life time and power saving, this product is expected to find new applications. Combining a high-quality AlN template with unique crystal growth technology, Dowa has been prepared for a mass production for deep ultraviolet LED chips, which boast the world’s highest output power in the disinfection wavelength of 280 nm.
