Prof. Jelena Vuckovic, Stanford University
“Optimized Quantum Photonics”
At the core of most quantum technologies, including quantum networks and quantum
simulators, is the development of homogeneous, long lived qubits with excellent optical
interfaces, and the development of high efficiency and robust optical interconnects for
such qubits. To achieve this goal, we have been studying color centers in diamond (SiV,
SnV) and silicon carbide (VSi in 4H SiC), in combination with novel fabrication
techniques, and relying on the powerful and fast photonics inverse design approach that we
have developed.
Our inverse design approach offers a powerful tool to implement classical and quantum
photonic circuits with superior properties, including robustness to errors in fabrication
and temperature, compact footprints, novel functionalities, and high efficiencies. We
illustrate this with a number of demonstrated devices in silicon, diamond, and silicon
carbide, including wavelength and polarization splitters and converters, power splitters,
couplers, nonlinear optical isolators, on chip laser driven particle accelerators, and
efficient quantum emitter-photon interfaces for color centers in diamond and in SiC. We
are also employing this approach to implement a quantum simulator based on color centers
in semiconductors.
Student Presentation by Bart Machielse (Electromechanical control of quantum emitters in
nanophotonic devices) will begin at 4:00.
Guest Presentation will begin at 4:30 PM.
Refreshments will be provided.
