SC478 - Microresonator based Optical Frequency Comb Sources and Integrated Waveguide Based Supercontinuum Generation
Tuesday, 11 May
10:30 - 14:30
Short Course Level: Beginner
Tobias Kippenberg, Ecole Polytechnique Federale de Lausanne, Switzerland
Short Course Description:
Optical frequency combs have revolutionized frequency metrology and spectroscopy over the last two decades. Recent advances have allowed generating optical frequency combs in compact optical microresonators using parametric interactions. This course will provide an introduction to the numerical simulation and design, operation principles and measurement techniques of micro-resonator frequency combs. The course will discuss in particular the formation of dissipative temporal solitons, and discuss how such states can be numerically simulated using the Lugiato Lefever equation. The course will discuss the similarities to soliton related phenomena known in supercontinuum generation, and will study basics of supercontinuum generation in integrated photonic waveguides, as recently studied. The course will moreover discuss applications of soliton micro-combs in ranging, communications and spectroscopy, and outline the state of the art.
Short Course Benefits:
This course should enable you to:
- Understand the basic principle of an optical frequency comb and its applications in metrology, spectroscopy and
- Understand how the basic Nonlinear Optics behind dissipative Kerr solitons
- Understand different operating regimes of Kerr frequency combs and its relation to nonlinear phenomena from Supercontinuum generation
- Understand how dispersion is measured and simulated in micro-resonators and waveguides
- Understand how to simulate microresonator frequency combs using the Lugiato Lefever equation
- Carry out nonlinear pulse propagation simulations for supercontinuum generation
- Understand the role of solitons in Supercontinuum generation
- Understand where the field of microresonator frequency combs stands today, and what the emerging questions and future opportunities are
Short Course Audience:
This course is intended for anybody interested in reviewing the basics of Kerr frequency combs, dissipative Kerr solitons and supercontinuum generation. The instruction will be at a level appropriate for graduate students and will assume some basic knowledge of lasers and nonlinear optics.
