Positions at Qubig GmbH
Applications are now welcomed for the QuRIOUS PhD position hosted by QUBIG (Munich)! To apply and find out more, please visit the QUBIG website.
Objectives:
QUBIG's expertise is to provide sophisticated tools for precise control of all properties of light, frequency, polarization, and amplitude. QUBIG has successfully developed extremely compact variants of two key elements: Electro-Optic and Acousto-Optic light modulators and, furthermore, already used them to create compact frequency references for cooling and trapping of Rb and Cs neutral atoms. The focus of QUBIG in this project is to extend this technology and create robust, field-deployable light conditioning modules for the control of the laser intensity and frequency in the visible regime.
1) Compact light conditioning modules for laser frequency control.
Task 1: The DC will learn QUBIG’s state-of-the-art technology for resonant SMD electro- and acousto-optic modulation and extend this concept to create broadband SMD light modulators for visible light. Task 2: The DC will investigate the feasibility of using the SMD broadband light modulators in combination with stable optical references (e.g, atomic vapors or ultra-stable Fabry-Perot cavities) to create a compact tunable laser frequency reference with integrated electronics.
2) Compact light conditioning modules for laser intensity control.
Task 3: The DC will use the SMD electro- and acousto-optic light modulators developed in Task 1 to create a light conditioning module for intensity stabilization and optical shutter with integrated electronics.The aim is to reach power stability better than 0.1% and shutting times shorter than 20 ns with an extinction ratio of at least 60dB.
3) Demonstration.
Task 4: demonstrate the use of the light conditioning modules on the clock developed by R2-UvA.
