Long-wavelength resonant antennas for enhanced radiation-nanomatter interaction and nonlinear optics

Luca Razzari

Institut National de la Recherche Scientifique (INRS), Canada

Optical antennas are resonators capable of enhancing free-space radiation into confined mode volumes. In this talk, a brief summary of our work on the use of such structures for boosting long-wavelength radiation-matter interactions will be given.

SOI multimode waveguide bend with radially bridged SWGs for broadband (de)multiplexing

Kevan K. MacKay, Winnie N. Ye

Carleton University, Department of Electronics, 1125 Colonel By Dr. Ottawa, Canada

We propose a novel broadband multimode waveguide bend that supports the propagation of multiple TE modes on a silicon-on-insulator platform. The gradient curvature bend utilizes trapezoidal subwavelength grating (SWG) segments, connected by adiabatically tapered radial strips to achieve efficient mode propagation. The bridged design offers an extra degree of design freedom, allowing the realization of a multimode bend with only one single etch. Propagation loss for all modes remains below 2.96 dB, and intermodal crosstalk is better than -19 dB across a broad bandwidth of 100 nm, centred at 1550 nm.

Existing OPAs are typically based on 2D rectangular arrays or 1D linear arrays. Both approaches present a limited field-of-view (FOV) due to the presence of the grating lobes when the element spacing is larger than λ/2. To address the need for an increased steering range, we propose a novel design of an OPA system utilizing a 2D circular phased array, with a substantially increased FOV. We present a circular OPA, with an 820-element array. A steering range ΩSR calculated as a solid angle of 0.51π sr.

Spatiotemporal beam shaping with nonlinear multimode optical fibers

Mario Ferraro, Fabio Mangini, Mario Zitelli, Stefan Wabnitz

Sapienza University of Rome

We experimentally study the spatial, temporal and spectral shaping of femtosecond pulse laser beams by using nonlinear multimode optical fibers. Conditions for the generation of walk-off solitons are revealed, and the self-cleaning of multimode Raman solitons is demonstrated. Exotic wave shaping phenomena include the spontaneous generation of rainbow spiral and helical beams carrying orbital angular momentum.
