Aluminum Gallium Arsenide

/ˌæl ɡæ əˈs/

noun — "the tunable semiconductor for optoelectronics."

AlGaAs (Aluminum Gallium Arsenide) is a compound semiconductor formed by combining aluminum arsenide (AlAs) and gallium arsenide (GaAs). By adjusting the relative composition of aluminum and gallium, engineers can precisely control the material’s bandgap, lattice constant, and optical properties. This tunability makes AlGaAs widely used in high-speed electronics, light-emitting diodes (LED), laser diodes, and photovoltaic devices.

Digital Subscriber Line Access Multiplexer

/ˈdiː ɛs ɛl æm/

noun — "the network junction that aggregates DSL lines."

DSLAM (Digital Subscriber Line Access Multiplexer) is a network device that collects multiple DSL connections from subscribers and aggregates them into a high-speed backbone link for transmission to an Internet service provider’s core network. It acts as a central hub that manages signal multiplexing, traffic routing, and line management, enabling efficient broadband delivery over existing copper telephone lines.

Gyroscope

/ˈdʒaɪrəˌskoʊp/

noun — "sensing rotation so you know which way is up."

Gyroscope is a sensor or mechanical device that measures or maintains orientation and angular velocity based on the principles of angular momentum. In modern electronics, gyroscopes are primarily used in inertial navigation systems, robotics, smartphones, drones, and other platforms that require accurate motion detection without reliance on external references like GPS. They provide critical data for maintaining stability, tracking rotation, and enabling precise control in dynamic environments.
