The Next Big Thing: IoT car network, photonics for smart car


Google and other major global information technology companies are competing to develop unmanned or autopilot; the Next Big Thing: IoT - Internet of things, car networking will also benefit various photonics products for it requires image, LiDAR, radar and other large quantities of optical and photonics products.Car photonics products include LED / laser intelligent headlights, OLED light source, car solar panels, car display / touch panel, HUD, reversing image system, driving recorder, full view auxiliary, LiDAR (Light Detection And Ranging), laser car distance measurement, LED / laser car communication, infrared night vision, fiber optic gyroscope, optical fiber communication inside the car and other dozens of products, smart car photonicss category is shown as below.

According to statistics of Strategy Analytics, in 2016 OEM value of ADAS is up to 17 billion USD, including photographic shots, ultrasound, Surround View, and night vision, lane departure warning (LDWS), head-up display (HUD), Telematics, Electronic windows, distance detection and automatic emergency braking (AEB), blind spot detection, and headlights etc, and it is expected to reach 28 billion USD in 2021.The compound annual growth rate (CAGR) during this period is 10%. With more than 70 million new cars built each year and their aftermarket (After Market. AM), these products will also increase market penetration year by year, and will eventually create a car photonics market of hundreds of billions USD. If Taiwan can account for 10% in the future, it is about hundreds of billions of NTD output.


The 10 biggest LED components manufacturers of the world in 2016


In 2016, the output value of LED components industry of the world obtained US$ 17 billion, a second year in decline since 2014. The combined revenue of the ten biggest LED components manufacturers of the world comprised 54% of the global market share. The figure meant that the concentration ratio was not too high, but the development pattern of these manufacturers was quite obvious.

In terms of revenue generated in 2016, the ten biggest LED components manufacturers (including epi-wafers, chips, packages and modules) of the world are (in the order from top to 10th) Nichia, OSRAM Opto Semiconductors, Samsung, Seoul Semiconductor, Epistar Corp., Everlight Electronics Co., Sanˇ¦an Optoelectronics Co., Forest Lighting, LG Innotek, Lumileds. Please see Table 1. Korea had three of these ten biggies, with Taiwan two, Europe two, China two, Japan one.

Because the two leading Korean LCD display manufacturers, Samsung and LG, have partially switched their products towards OLED products, their subsidiariesˇ¦ output values exhibited declines, rolling back to the third and ninth rankings (with LG Innotek dropping by two spots).


Scientists reduce the photobleaching effect in STED microscopy with the use of Onefive sub-nanosecond laser Katana HP


The Molecular Microscopy and Spectroscopy group togheter with the Nanoscopy group at the Istituto Italiano di Tecnologia (IIT, Genova, Italy) have significantly reduced the photobleaching effect in STED (STimulated Emission Depletion) microscopy without the reduction of the spatial resolution by combining the time-gated detection technique with the use of the subnanosecond fiber laser Katana HP as STED laser beam [1]. This result brings one step further the development of commercially available super-resolution microscopes.

The Katana HP laser offers the capability to be externally triggered. This capability allows to synchronize and temporally align the STED pulses to the excitation pulses with the simple use of an electronic picosecond delayer. For these reasons, the use of the Katana HP laser as STED laser significantly reduces costs and complexity of a STED microscope with respect to the use of stretched pulses from a mode-locked femtosecond laser.

The STED super-resolution microscopy technique, which was awarded the Nobel Prize in Chemistry in 2014 (Prof. S. W. Hell), makes use of the photophysical properties of fluorescent probes to achieve nanometer-scale spatial resolution, well below the limit imposed by the diffraction of the light. It can thus reveil details that have not been visible before. In particular, STED microscopy is based on the ability to control the fluorescence emission of the probes in time and space by the superposition of a red-shifted STED laser beam to the excitation beam of a conventional microscope.
