PHOTONIC CHIP STEERS LIGHT WITHOUT ANY MOVING PARTS

In search for a compact and reliable LiDAR solution, researchers from Yokohama National University in Japan have developed a waveguide-based photonic chip that takes a laser beam as an input and steers light beams over a wide range of selectable angles, without involving any moving parts, not even MEMS. by Julien Happich @ eenewseurope.com Their results

LASER BEAM WIRELESS SMARTPHONE CHARGERS: THE NEXT BIG THING

Cellphone chargers have been in existence for years and have grown from one stage to another. It started with the mobile phone traditional charger which had a USB interface, a DC converter, and a charging plug and now has expanded to a close-range inductive wireless charging. The commonly used inductive wireless charging is nice but

Laser show for poor man using PIC18F1220 microcontroller

Laser show for poor man Here’s another useless but cool looking “must build” gadget for every romantic geek. Let me introduce PIC microcontroller based three axis laser spirograph. Step 1 Gathering stuff Design is quite simple and employs regular parts and components but you are free to change/modify it in way you like. At first

Building your own Simple Laser Projector using the Microchip PIC12F683 Microcontroller

The 8 pins PIC12F683 microcontroller is one of the smallest members of the Microchip 8-bit microcontroller families but equipped with powerful peripherals such as ADC and PWM capabilities. This make this tiny microcontroller is suitable for controlling the DC motor speed. In order to demonstrate the PIC12F683 capabilities and to make this tutorial more attractive,

Lasers built on silicon are a step towards fully integrated photonics

It has long been predicted that inter-chip and even intra-chip data links must ultimately move from the electrical to the optical domain. Prior work in the field has typically involved lasing light sources being fabricated separately from, and tightly coupled to, a host IC. A group of researchers from the UK has demonstrated the first

Marantz CD63SE laser transport mechanism replacement

An elderly, but still sought after Marantz CD63SE was bought into the shop last week, with the fault reported that CD’s would no longer play. After approximately 15 years of use, this is a common situation, as the laser power will gradually reduce over time to the point where it can no longer focus reliably

Repair of Arcam CD73 laser mechanism

This 2004 vintage Arcam CD73 came into us with the reported fault that it would no longer play CD’s, or even read the table of contents. Given that it is over eight years old and had plenty of use in that time, we were not surprised to find that the laser had expired and needed
