The sixteen DFB lasers, each with a wavelength spacing of 100 GHz, are arranged in a 4×4 matrix. The wavelengths are designed using an interleaving scheme to reduce grating crosstalk. The grating is ...

This proposed chaotic laser consists of a distributed feedback (DFB) laser section, a phase section, and a DBR section. DBR grating can provide wavelength detuning to generate mode beating, which ...

MOCVD machines are usually used for GaAs epitaxial regrowth, depositing semiconductor layers onto a wafer’s substrate surface and DFB laser grating. A cladding and cap layer ‘sandwich’ the active ...

In 2014, the US Navy installed its first prototype SSL (solid state laser) capable of countering surface craft and unmanned aerial vehicles (UAVs) on a Navy ship. The Navy since then has been ...

BluGlass, a company pioneering lasers for the quantum, defence, and biotech markets, has filed three US patent applications (provisional patents) for next-generation high-power, tuneable GaN lasers, ...

The best color laser printers are a great investment that can save you time and money compared to cartridge-based inkjet printers. Laser printers use toner, which lasts a long time, delivering a ...

Credit: Chinese Academy of Sciences HELSINKI — China could look to laser power transmission from lunar orbit to supply spacecraft on the moon and solve one of the big challenges for its lunar ...

Scientists have observed “bending” atoms using a crystal grating—an experiment once ... On September 14, 2015, for the first time ever, the Laser-Interferometer Gravitational-Wave ...

The best laser printer is often the top choice for office and home office use. Excelling at document printing, laser printers have a reputation for producing crisp text, fast print speeds ...

If shaving is growing tiresome, consider laser hair removal: This method damages hair follicles to reduce growth over time, ultimately giving more long-term results than using a razor. After ...

The best laser printers on the market are those that reliably deliver pages of high quality at lower printing costs than the competition, without causing you headaches. I know because my team ...
