Nonlinear Nanophotonics: Towards Few-Photon Interactions

Nonlinear optical interactions are essential for many quantum optical functions such as the generation and temporal/spectral manipulation of single and entangled photons, as well as enabling devices such as phase-sensitive parametric amplifiers and parametric oscillators, networks of which are applied in coherent Ising machines.

 

Thin-film lithium niobate (TFLN) has emerged as a key nanophotonic platform for these applications, with tight optical confinement enabling both strong nonlinear coupling and dispersion engineering for efficient broadband interactions, as well as dense integration with essential linear components like couplers, fast electro-optic switches, high-Q resonators, etc.

 

Examples of TFLN devices and prospects for nonlinear optics operating at the few-photon level will be presented.

Prof. Fejer joined the Stanford faculty in the Department of Applied Physics in 1986. His group’s current research is in the fields of nonlinear, ultrafast, and guided-wave optics, micro- and nano-structured ferroelectric and semiconductor media, and precision optical measurements, with current projects in classical and quantum optical signal processing, ultrafast optics, efficient generation of coherent visible and infrared radiation by waveguide and bulk optic frequency conversion, precision interferometry for gravitational wave detection, and characterization of materials with low-dissipation.
