Low-power optical device achieves around 100 times amplification using just a couple of hundred milliwatts of input power ...

A new Stanford-designed optical amplifier uses energy recycling in a resonator to deliver strong, low-noise amplification with far less power.

All, I posted this at DIYMA, and didn't get too may helpful responses, so figured I'd ask the Hive Mind. Back in the '90s, I used to set amp gains by turning the level pot all the way up and then ...

Dubbed the market’s first car audio amplifier with digital input, the TDA7801 addresses the trend towards a fully digital head unit and sound systems, delivering numerous advantages over systems based ...

Light does a lot of work in the modern world, enabling all types of information technology, from TVs to satellites to fiber-optic cables that carry the internet across oceans. Stanford physicists ...

Close up of an optical amplifier chip, similar to the one detailed in this study, that is being developed in the lab of Stanford physicist Amir Safavi-Naeini. A red laser light shines from an optical ...
