Fabless services for PICs in indium phosphide launched


A wafer foundry, a consultant in III-V photonics, and a PIC design house will now offer fabless development into production services for customised PICs in indium phosphide (InP).


The joint service comes from Global Communication Semiconductors (GCS), a compound semiconductor wafer fabrication foundry; Intengent, a consultant in the area of III-V photonics; and VLC Photonics, a photonic integrated circuit (PIC) design house. GCS provides a broad range of wafer foundry services based on a regrowth-free process in InP. Originally developed as an opto and heterojunction bipolar transistor (HBT) processes, it also allows for prototyping and volume-scalable production of PICs. The key enabler is a photonic integration


platform compatible with the foundry’s regrowth-free process and yet suitable for several applications. Intengent has developed such a platform, termed Taper Assisted Vertical Integration (TAVI), which is regrowth-free, based on the GCS process,


and enables the decoupling of epitaxial growth and wafer fabrication. TAVI covers many PIC applications, including those in growing and emerging markets, like optical interconnects and switching markets. It offers complementary solutions to silicon photonics, which is considered by many the technology of choice for high-scale integration but lacks amplifying, lasing, and other functions naturally implementable in InP. In a three-way partnership with GCS and VLC, Intengent is working towards making TAVI a generic platform while preserving its openness to PIC customisation. A process design kit created by VLC Photonics lowers the PIC design risk and effort, focusing on circuit-level simulations. Brian Ann, CEO of GCS, said: ‘Our well- established Opto and RFIC processes have great synergies with the TAVI PIC platform. Our four-inch, and six-inch wafer capability as well, based on a commercially supplied one-step-growth epitaxy, creates a unique opportunity for PICs in InP.’


Machine maker Trumpf has acquired Aachen-based ultrashort pulse laser manufacturer Amphos to strengthen its own technology offerings. Amphos was founded in 2010 as a spin-off of RWTH Aachen and the Fraunhofer Institute for Laser Technology ILT.


Trumpf acquires ultrashort pulsed laser manufacturer It develops and produces


the lasers using its own InnoSlab technology, originally developed by its founders while they were still part of the Fraunhofer institute. With it they are able


to achieve high output powers for manufacturing and research applications.


THE FUTURE DEPENDS ON OPTICS


The technology will allow Trumpf to open up a new range of parameters for its ultrashort pulsed lasers. Amphos’ ultrashort pulsed


lasers offer output powers between 200W and 400W, with its additional high- power lasers for research applications reaching as high as 1.5kW.


Aledia raises €30m for nanowire LED technology


French manufacturer of display LEDs, Aledia, has completed a €30 million series C financing round, including investment from Intel Capital. Aledia's 3D LEDs are based on a gallium-nitride-nanowires- on-silicon platform. Aledia is developing


a new generation of LEDs for mobile display applications manufactured on large-diameter silicon wafers (200mm, scalable to 300mm). It is expected

to lead to more efficient, brighter displays that can be manufactured at a moderate cost. The silicon-based


technology is also well suited for the integration of electronics. ‘Energy efficiency,


display quality and cost are three critical characteristics of mobile consumer electronics displays, and we feel Aledia’s 3D LED technology, based on large- area silicon fabrication, can


impact this space,’ said Gregory Bryant, senior vice president and general manager of the Client Computing Group at Intel. In addition to working


on a new generation of displays for smartphones, laptops and tablets, Aledia is also working on smaller displays for virtual reality, augmented reality and smartwatch applications, using its megapixel integrated silicon chips.
