Target class: semiconductor laser Context triple: [quantum cascade laser, instanceOf, semiconductor laser]
-
A.
compound semiconductor
A compound semiconductor is a semiconductor material formed from two or more different elements (such as gallium arsenide or indium phosphide) whose combined properties enable specialized electronic and optoelectronic device performance beyond that of elemental semiconductors like silicon.
-
B.
optoelectronic device
chosen
An optoelectronic device is a component or system that converts electrical signals into light or light into electrical signals, enabling functions such as sensing, communication, and display.
-
C.
III-V semiconductor
A III-V semiconductor is a compound semiconductor made from elements in groups III and V of the periodic table (such as GaAs or InP), valued for its direct bandgap and high electron mobility in high-speed and optoelectronic devices.
-
D.
laser cooling device
A laser cooling device is a system that uses precisely tuned laser light to reduce the kinetic energy of atoms or particles, thereby lowering their temperature to near absolute zero for experimental or technological applications.
-
E.
optical component
An optical component is a physical element designed to manipulate light—such as by transmitting, reflecting, refracting, focusing, or filtering it—within an optical system.
- F. None of above.
Provenance (1 batch)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
