Attosecond electronics in semiconductors – ATTOCOM

The ATTOCom project aims at understanding and controlling the attosecond emission from band gap semiconductors. Amplitude and spectral phase characterization would open key issues in controlling quantum systems on attosecond time scales. This plays a fundamental role in the future development of petahertz electronics and novel attosecond sources. The objective of this proposal is to control the attosecond emission from band gap semiconductors in the UV to the EUV (4-20 eV). On top of gaining knowledge for future petahertz electronics, we will create the first all solid state source of isolated attosecond pulses controlled by the crystal nature and the laser light wave properties. For this, we will: 1) Reveal that the harmonic emission in semiconductors switches on attosecond time scale 2) Establish attosecond metrology down to the UV; 3) Elaborate theoretical support to operate attosecond science in semiconductors.
