1) A semi-stable fundamental particle with negative electric charge and a spin of ½

2) The technology of transmission, control, and detection of light(photons)

3) One thousandth of a picosecond

4) The addition of impurities to another substance, usually solid, in a controlled manner that produces desired properties

5) A conducting or dielectric structure able to support and propagate one or more modes

6) Any material that resists the flow of current

7) A device used to amplify a signal or open and close a circuit

8) Devices that use the electron spin instead of the electron charge for electronics

9) The portion of he electromagnetic spectrum with much longer wavelengths than infrared radiation, typically about 1 mm

10) A clock that offers an extremely high-frequency precision and stability, exceeding the performance of the best cesium atomic clocks
