Abstract

Chalcogenide glasses (ChGs), namely the amorphous compounds containing S, Se and/or Te, are emerging photonic materials known for their broadband transparency, high refractive indices (n≈2–3.5), large Kerr nonlinearity and low two photon absorption. Therefore, ChGs have been recognized as ideal materials for achieving high-performance nonlinear photonic devices. In particular, on-chip ChGs-based nonlinear photonics with unparalleled advantages in terms of small size, low cost, robustness and high performance have been one of the most well-studied hotspots in recent years.

In this talk, we will present our recent research progress on on-chip CHGs-based nonlinear photonic devices using 2D-material passively mode-locked fiber lasers. The main works include as follows. First, we developed several kinds of 2D-material passively mode-locked fiber lasers with the spectral range of 1–2 μm and the pulse width from ps to fs. Second, we used the 2D-material mode-locked fiber lasers to efficiently pump on-chip ChGs waveguides or microresonators, and a few of on-chip nonlinear photonic devices or systems will be demonstrated including 1) supercontinuum source integrated on-chip spectroscopic sensor, 2) on-chip optical frequency combs based on cascaded four-wave mixing, and 3) on-chip Raman soliton generation.
