We present the concept and design, and we report on the experimental performance of a broadband Variable Optical Attenuator (VOA) for integration with large-core rectangular multimode waveguides. Operation of an individual 221 mu m x 111 mu m optical waveg ...
Position measurements of mechanical oscillators underpin experiments spanning from applied nanoscale sensing to endeavors aiming to resolve open fundamental problems of modern physics. Sufficiently precise position measurements are also used for engineerin ...
Recently, microresonator-based dissipative Kerr soliton frequency combs ("soliton microcomb") have emerged as miniaturized optical frequency combs. So far, soliton microcombs have been realized in many CMOS-compatible material platforms including silico ...
In quantum mechanics, the Heisenberg uncertainty principle places a fundamental limit in the measurement precision for certain pairs of physical quantities, such as position and momentum, time and energy or amplitude and phase. Due to the Heisenberg uncert ...
Quantum Integrated Photonics (QIP) harnesses quantum-states of light on tiny chips, from generation to processing and eventual detection. Within this context, this thesis explores functional QIP elements resulting from the monolithic integration of semicon ...
A device capable of converting single quanta of the microwave field to the optical domain is an outstanding endeavor in the context of quantum interconnects between distant superconducting qubits, but likewise can have applications in other fields, such as ...
The thermomechanical properties of materials are among the most important properties for
designing precision instruments, in particular for devices seeking high-dimensional stability,
invariant temperature-elastic properties or low thermoelastic losses. De ...
Complex yet compact nanoscale mechanisms have largely been absent due to the rather limited availability of components and integration techniques. Especially missing have been efficient interconnects with adjustable characteristics. To address this issue, ...
Emerging compositionally engineered complementary metal-oxide-semiconductor (CMOS)-compatible platforms have been employed for high efficiencies in various on-chip applications, including optical parametric amplification and wavelength conversion. Combinin ...
We report on the use of low-loss Si3N4 waveguides for efficient frequency conversion tunable from the near infrared to the short-wave infrared. We achieve -15 dB conversion efficiency for 200 mW coupled pump power. ...
