With the explosive growth of data traffic, the market is extremely eager for hybrid photonic integrated circuits that can combine various optical components on a single chip.Silicon is an excellent material for photonic integrated circuits (PICs), but achieving high-performance laser sources in silicon still poses challenges. The monolithic integration of III-V quantum dot (QD) lasers on silicon i...
ARRI has launched Orbiter Beam, further expanding the range of accessories for LED spotlights. This is the first beam optical device in the ARRI LED lighting product portfolio. A new optical concept has been developed specifically for this reflector. The beam intensity level of Orbiter Beam has an output comparable to the ARRI Daylight M series M18 at a more compact beam angle.These high-intensity...
The Near Infrared Red Planet Search Alliance, jointly managed by the Department of Astronomy at the University of Geneva and the University of Montreal, has received cutting-edge advances in CSEM laser frequency comb technology.The laser frequency comb is a precise and stable light source designed to help the NIRPS alliance unravel the mysteries of distant planets, including the possibility of sea...
The new architecture based on metamaterials provides a promising platform for constructing large-scale production and reprogrammable solutions that can perform computational tasks using light.The idea of simulating computers - a device that uses continuous variables instead of zero sum ones - may evoke outdated machinery, from mechanical watches to bomb sight devices used in World War II. But emer...
Hybrid 3D integrated optical transceiver. (A, B) Test setup: Place the photon chip (PIC) on the circuit board (green), and glue the electronic chip (EIC) onto the top of the photon chip. (C) It is the cross-section of the EIC-PIC component with micro protrusions. (D) Display the mesh of the finite element model.The latest progress in artificial intelligence, more specifically, is the pressure plac...
